Compaq Security Enhancements for Microsoft Windows 2000

by dave.g4ugm＠gmail.com

Whilst sifting through the loft I came across this brochure https://1drv.ms/b/s!Ag4BJfE5B3onmNYe9v2yiv2abf2Afg?e=0EjFbM for the Compaq Security Enhancements for Microsoft Windows 2000, which evolved from the Digital product "Secure NT" I wonder if any one actually used these products and can talk about them?

IBM 3270 compatible terminal connected to Hercules IBM mainframe emulator.

by mattislind＠gmail.com

I have been working on a project for some time to connect a IBM3270 compatible Alfaskop terminal with its IBM 3274 compatible cluster controller to the Hercules mainframe emulator. Yesterday I eventually succeeded. I was able to login to TSO on my Hercules system that ran MVS 3.8j. Here are a couple quick video clips: https://youtu.be/H1Sxt7xjn4Y https://youtu.be/CFfB3yCN9OI To achieve this I created a small piece of hardware I called SyncDongle, essentially it's just a few level converters, connectors and a STM32F103 blue pill. On the hardware I run a small piece of firmware, BSCBridge. It bridges between the sync serial BSC used by the Alfaskop cluster controller and the BSC variant that the 2703 emulation inside Hercules is using. More information here: https://github.com/MattisLind/alfaskop_emu and here http://www.datormuseum.se/peripherals/terminals/alfaskop There are good chances that the SyncDongle/BSCBridge combo could work with a 3274 or 3174 controller as well but I haven't tested since I don't have one. But no guarantees given, though. If someone has a spare 3174-51R, -61R, -81R or -91R I would be very interested in it. Actually there is a good chance that it could work with general BSC use. Maybe for NJE between Hercules and a real IBM machine? Or 2780/3780 RJE terminals? Or other third party 3270 terminals using BSC. The BSCBridge firmware only supports non transparent mode at this point, it works fine with Alfaskop since it does not support anything else. Maybe a showstopper for 3174 with 3279 terminals? SHouldn't be that difficult to add transparent mode if needed. /Mattis

SunBlade 100 keyboard issues

by technoid6502＠gmail.com

I have a Sunblade 100, got it on ebay for $103.00, landed on my doorstep. I hacked the nvram chip with a pair of AA batteries, which should keep the thing going for a hundred years. I really wanted a STOP key, and found an ad on Ebay for new Type 7 usb keyboard/mouse, bought the set. I used a plain jane USB keyboard to install OPENBSD and that works just fine. The type 7 keyboard works great on a pea sea, and, if the Sun is booted, running an operating system, it works fine there too. If the type 7 keyboard is plugged in at any time prior to booting from media, any time the OpenBoot prom is in charge, the prom reports no keyboard detected and defaults to a serial console. This happens even if the type 7 keyboard is plugged in ALONG WITH the generic USB keyboard I am using successfully with the machine right now. An advertisement for the type 7 keyboard gave me a clue that this is a known problem with some early SunBlade machines and that I would need a Firmware upgrade. I've looked on Oraclle's site for Sunblade 100 firmware upgrades and not found them. Can someone link me to the latest firmware for the SunBlade 100 so I can get it to recognize this keyboard? At present I've got OpenBSD 6.7 running with X and a light window manager. Got Dillo running as well, so I can surf. Woot woot! I miss my SParcstation 4/330 though. Thanks! Jeff The OpenBoot Prom utility however, does not see this keyboard at all. I

Curt Vendel

by technoid6502＠gmail.com

It is apparently true. He had heart troubles, but this was unexpected and certainly a shock to his family. I met Curt here, on Classiccmp, about twenty years ago. We are both hardcore Atari 8-bit computer geeks, but we met in this forum. He is missed by many as he touched many. Please pray for his soul and for peace for his wife and children. Jeff

Fwd: Factory Rodent Urine, was Re: Sun SPARCstation LX boot from CDROM?

by ccth6600＠gmail.com

---------- Forwarded message --------- From: Tom Hunter <ccth6600 at gmail.com> Date: Tue, Sep 1, 2020 at 2:17 PM Subject: Re: Factory Rodent Urine, was Re: Sun SPARCstation LX boot from CDROM? To: Chuck Guzis <cclist at sydex.com> Thanks Chuck, Unfortunately it is well past cleaning. The lead/tin alloy has corroded into a hard oxide with very high melting temperature. Lead oxide melts at 800+ degrees C and tin oxide at 1300+ degrees C. This is well past the 300 degrees C a soldering iron produces. Most importantly the copper pads below and some of the tracks are gone completely. About 70% of the board is pristine. Only the section which has been exposed to the liquid is corroded. I can't say for sure that it is rodent urine, but when I tried to reflow the corroded solder joints it faintly smelled like my firewood where rats nested one winter. Of course there is no chance for a rat or even the tiniest mouse to get into a fully assembled Sun/Sony CDROM with the affected PCB side facing down and somehow urinate upwards towards the PCB. As the drive was never before disassembled it could only have happened during manufacturing. 20 years ago when I put the drive and other SPARX LX gear into my display cabinet I could have easily found a replacement. Now it won't be easy. The sad thing about it is that everything was pristine when I put it in my cabinet.

Looking for an IDE simulator

by jnc＠mercury.lcs.mit.edu

After having a run of almost half a dozen IDE hard drive failures recently in a short period of time (on my older desktops which use them, I've decided that I should see if there's an IDE emulator (using SD cards) available I could switch to. (I'm not sure why I had so many failures in such a short period; I can only conclude that they're too old now, and reaching the end of their service lives. So soes anyone have one (or more) they can recommend? (IDE simulators only; I don't want to have to mess around changing anything more than I _absolutely_ have to)? I did find these guys: http://store.mesanet.com/index.php?route=product/category&path=74_64 in an online search - the CFADPTHD seems like it's close to what I'd want, except it's Compact Flash; I'd have preferred SD but I guess converting their interface to IDE is more work.

Sorry, I did not see your post that there was no concern of losing Michael?s SWTPC content. I simply did not want to see more great material disappear from the internet as our peers age and become unable to maintain their web presence. I?ve seen that happen over and over now. I?ll remove my mirror of Michael?s SWTPC content. You can contact Michael Evenson and let him know his assistance in preserving the content for the benefit of the hobby community is also ?unauthorized.? I presently pay for 150Gb of bandwidth on deramp.com to host material for vintage computing hobbyists. I?m surprised the swtpc.org bandwidth requirements are high enough to be an issue that requires your ?grace? to allow us to view its content. Mike

swtpc, mikeholley, early computer stores

by jwest＠classiccmp.org

Contacts have been made to secure disposition of Bill Dawson and Mike Holley's site/contents. As part of that effort, I pointed swtpc.org to what used to be swtpc.com (and also swtpc.org). So if you go to swtpc.org you can traverse both sites. But that is not why I'm posting.. So in doing this and fixing a few links, I noticed there was a lot of pictures and info on "first computer store in..." information, apparently written by Mike Holley and we were just talking about that topic here. Some may want to go hunting for the computer store that was an adult movie place heh J

Looking for MIPS Magnum R4000 or compatible

by seanellis9＠gmail.com

Hello all, apparently I've been in this group now for weeks but my spam filter thinks it's all spam. Fixed that, I hope. Does anyone have any leads on a MIPS Magnum R4000 or Jazz-compatible machine? I've been working for a while on trying to round out my collection of alt-arch WinNT machines, and the Magnum has proven to be the most elusive. Thanks

michael Holley?

by jwest＠classiccmp.org

I need advice on a path forward then. From emails I got from Michael, Bill Dawson gave him authority over both swtpc.com and swtpc.org. Originally, Bill Dawson had swtpc.com but Michael was managing/uploading much of the content there under the mholley subdirectory (www.swtpc.com/mholley). Michael registered swtpc.org and I set that as a redirect to the subdirectory on swtpc.com. Michael stated that at some point the sites would be merged and he would be the sole site maintainer. So now I am hosting swtpc.com and swtpc.org, and ownership of the site is up in the air. Whoever owns swtpc.com doesn't have an A record, which effectively kills off swtpc.org (redirect fails) as well. All that good content (and there's a fair amount) is no longer accessible. I see herb johnson ripped the site and has a copy over at deramp, but no clue if that is a complete copy that descended from Bill or Mikes wishes. My initial plan - since I have no registrar access to swtpc.com and it doesn't point to my name servers, nothing I can do. But swtpc.org at least still, is pointing to my nameservers. I will change the apache config from a redirect to the real contents (but not sure if it should bring up the content that was swtpc.com or swtpc.org). At least a real site will be up. That being said, I am moving the sites I host free from one server to another. That project is ongoing the past few days. I would like to move swtpc.* as well, but see above. If someone has a reasonably cogent claim to the content I would hand the site (both) to them. If it's long been gone and other copies are complete and commonly used, then I could just delete it but hesitant to do so. I would like to decommission the old server but this should be resolved first. Feel free to send me advice/thoughts/claims/rants off-list. J

CYCLOID faceplate for Altair computer...

I decided to get a tvga8900 for mine, as fiddling with 15khz ttl is just too flaky and problemmatic.

I remember this very well. I was living in Santa Monica at the time, and drove down Pico Boulevard almost every day. Needless to say, I immediately noticed the "Computer Store" sign and stopped in, soon becoming one of the regular "hangers on". Dick Heiser and his wife Lois were taking a big chance, but it proved to be a good bet. Initially, their business consisted of buying Altair 8800 kits and assembling them in the back of the store. A lot of people were happy to pay extra to not have to solder all those hundreds of connections. Dick was a regular fixture at meetings of the Southern California Computer Society (SCCS), often making deliveries and taking orders there. In those days, SCCS monthly meetings were *the* place for computer geeks to get together and exchange news and get help. A few months later, two guys named Steve showed up at a meeting with a kit they called the "Apple I", for the grand price of $666.66. I wish I had had the foresight to buy one! Instead, I wound up joining the SCCS group purchase of DEC LSI-11 systems. I still have that system, with a case and power supply from a TRW surplus sale. It isn't worth nearly as much as an original Apple I, though! :-) Alan "Hindsight is 20-20" Frisbie

The answer tells us whether they were explicitly > planning on making other models later! I honestly do not recall if they used the "I" or not. This was, after all, 45 years ago! At that time there were many tiny startup companies trying to get our attention, most of which sank without a trace. If I had been asked back then which ones I thought would survive, I probably would not have picked Apple. Not my first mistake, and certainly not my last. :-) Those *were* exciting days, with new products and developments happening every month. I looked forward to every SCCS meeting, with people showing off their latest homebrew project, swapping tips, and buying parts & boards. For a while, there was even a large wheel of cheese which we eagerly devoured. :-) Alan Frisbie

"That might be true for discussions where people don't care to do any research, or where words like "first" are uses more for hyperbolic emphasis, but suggesting someone started an industry on a list like this, I think, doesn't seem out of place." I agree that using ?*first**?* has a certain connotation. However, until it is proven otherwise it?s quite appropriate. If this word were not used, by me or anyone else, on this website then we never get to learn anything ? *new*?. Even in historical writing, of which I?ve done some as a historian, one has to acknowledge a source, but I for the life of me can?t remember as I didn?t have the source on my electronic-research rolodex. In such an occasion, as the note I sent to cctalk, should have stated this. My apologies. Happy computing!

Diskless VMS install

Hi, I have a VAXstation 4000/60 with an internal disk but no CD drive. I'd like to install VMS (7.3), but I'm new to VMS. I have a SIMH VAX instance running on the same LAN with VMS installed (mounting the VMS images is easy, of course). Can anyone point me to a HOW-TO which explains how to use one VMS system to MOP / netboot another system to install VMS? Thanks, John

You can see it better here: https://twitter.com/AnachronistJohn/status/1294725819038752768 I use a SATA to IDE adapter, then an IDE to UW-SCSI adapter, then an UW-SCSI cable and terminator, then finally a 68 to 50 pin adapter. The previous drive was a Samsung SSD, but I think that constant, non-stop swap use wore it out. This was the smallest new spinning rust drive I could find. SCSI2SD would work for a while, but, again, swap usage would wear out an SD card in no time, I'm sure. John

Early Computer Storefront Photos

by marvin＠west.net

I sent an email to Al asking if he wanted them, and no response which I took to mean no :). There are about 40 photos of the fronts of computer stores circa 1977-1978, and were taken by a friend of mine who was a computer salesman at the time. Most (all) are date stamped and have the store location written on the back. None for Santa Barbara :), so I'll pass them along to whoever wants them. And Al still has first shot at them if he missed my original email. $1000 with free postage, or free if you pay postage :). Priority mail should run about $8.00.

Computer Stores

by wayne.smith＠charter.net

The LA Times called it the first computer store in a story in December 1975. The first ad for the store ran in July of that year.

old data books?

by uban＠ubanproductions.com

I'm trying to reduce the amount of "stuff" I have and I've been carrying around a significant number of old data books. My plan has always been to have all of the resources I need in my retirement (assuming I get there) to work on and repair the various vintage computing hardware I've also collected over time and have been storing. My question is if I this information is all now available online or if I need to keep these data books. My guess is that it is some of both. Also, if I decide to part with these, should I create a list and make them available for the cost of shipping or just recycle them? Maybe someone collects them? --tom

Dolch (DLI) Logic Analyzer C100 Disassembler Roms?

by holm＠freibergnet.de

Hi guys, I have three Dolch Logic Analyzers, the two bigger ones are Palas <someting> Analyzers, one of them with an highspeed option, the third is an Compact 100 Analyzer. For the bigger ones I have Disassemblers for 8080/8085 and Z80 as far as I know. I want to use the C100 with a Z80 disassembler, but the ROM images are different it seems, the roms don't work in the C100. Has anyone the rom images for the C100 Z80 disassembler?

Computer stores

by c.murray.mccullough＠gmail.com

45 yrs. ago last month, mid-July, Dick Heiser started a new industry, the retail computer store. It opened in West L.A. under the name Arrow Head COmputer Company. aka, The Computer Store. This began the direct marketing of microcomputers to hobbyists, later to the masses of the middle class, albeit a small market 45 yrs. ago. Happy computing. Murray ?

SIMH on low overhead platform

by ccth6600＠gmail.com

Has SIMH been ported to a low overhead (instant-on) platform? I ask the question because the startup time of Linux is distracting when powering on a PiDP-11/70 or similar clone systems based on SIMH. Thanks Tom Hunter

Alto II keyset connector plug identification

by steven＠malikoff.com

Would anyone be able to identify the 19 pin connector used on the Alto II keyset? Shown in the second photo on https://www.computerhistory.org/collections/catalog/X124.82C The Xerox engineering doc (209962B_Alto_II_Assembly_Keyset.pdf) has it as P/N DE51218-1 if I interpret it correctly. I've looked for a while and the closest I can find appears to be Mouser p/n 2DEF19P The cost of 136 USD (each!) is more than I (and perhaps everyone else) would really like to pay, and that's only for the male end. Ideally I would like a datasheet on this original connector if possible, to know the pin-pin spacing and the pressed metal surround dimensions. I've just ordered small trial quantities of screws, microswitches, e-clips, nutserts, rods and so on for my keyset lookalikes/workalikes. Also about to start the key mapping to F5-F9 using a popular small SOC board, which is small enough to be inside a custom printed shell that the keyset plugs into. That is, the 3-row 19-pin female connector side which goes through to USB. I was thinking there's no reason it shouldn't be able to work using the original connector with a real keyset-less Alto, should any such animal be lurking out there. Hence looking at the feasibility of placing in a 19 pin male-female connector arrangement rather than the fallback of straight-through to USB. The whole thing is still at prototype stage so even if it doesn't work out, well I will at least have a bunch of additions to my nuts/bolts/fasteners/switches stash. Thanks for any help, Steve.

Network gear that supported StarLAN 1 (not 10)

by classiccmp＠crash.com

I was wondering if anybody remembers which networking vendors supported StarLAN 1, or 802.3e / 1Base5, back in the 1980s? Hoping to get product names and/or model numbers. I've come across some references to Western Digital, Micom-Interlan, Cross Comm Corp (Massachusetts), and Fox Research (later DCA?) possibly having offered products to bridge StarLAN to Ethernet. But in the few cases where I've seen a model (ex. Cross Comm 487 Series) I haven't been able to get past blurbs in Info World. I have one host interface, expect more to arrive shortly, and would love to track down a bridge/switch/router that might allow me to make them reachable from Ethernet. Thanks, --Steve.

SIMH on low overhead platform

It's funny, but it seems to be true that the pricier hardware takes longer to POST. I bought several AMD AM1 CPUs / motherboards when a set only cost $50 and I use them as routers running NetBSD. From power on to booting the kernel is less than three seconds. Getting to fully multiuser is less than 30 seconds, even with DHCP. > Oh yeah, NetBSD 9.0-stable 64-bit also only takes a few seconds to boot > on a Raspberry Pi 3B+.

An RPi4 with 4 or 8GB of RAM should be a very > nice turnkey SIMH server. Yes, the Pis boot very quickly. The Pi 4 is supported, but just not in NetBSD 9. The Pi 4 takes a wee bit longer to boot because it uses UEFI, but I think the difference in performance is well worth the extra few seconds. https://github.com/pftf/RPi4 https://twitter.com/AnachronistJohn/status/1287628712981049345 A bonus is that you can boot directly off of USB attached storage (although I'm still loading UEFI and the kernel off of the SD card). SIMH runs very well on the Pi 4. John

UniSys ClearPath OS/2200 Express?

by Kevin＠RawFedDogs.net

Classic Computer Fans, Technically this isn't a classic OS, but I suspect its lineage goes back far enough to be of interest. Has anyone tried out UniSys ClearPath OS/2200 Express? https://www.UniSys.com/offerings/clearpath-forward/clearpath-forward-produc… I normally don't run Windows at home, but have set up a Windows 7 VM to try it out. It includes a few PDFs, including basic startup and shutdown procedures. I haven't found any intro to OS/2200 type docs yet. If anyone knows of any, please let me know. It looks like it could be an interesting system, if I can ever learn my way around. -- Kevin http://www.RawFedDogs.net http://www.Lassie.xyz http://www.WacoAgilityGroup.org Bruceville, TX What's the definition of a legacy system?

Sun Ultra 10 - openBSD 6.7+Creator3D+sunffb: Xorg and xenocara freeze the system

by bvasea＠gmail.com

Greetings. I would like to solve a mistery regarding graphical user interface on a Sun Ultra 10+ Creator3D UPA graphics card, running OpenBSD 6.7/sparc64. Everything works fine with Solaris 10. Did anybody manage to get X running on openBSD? Sparc64 support is somehow bogus so I feel that if I talk to them, there will be no answer. Here is what I am trying to do and hope will help others: - installed openBSD on two Sun Ultra 10 machines: one machine full install (with X packages), the other without X, but xenocara compiled later; - Configured /etc/X11/xorg.conf as described in attached file 1; The same issues were observed for both Xorg and xenocara, so I suspect there's something wrong with sunffb: - /var/log/Xorg.0.log shows everything is in order (except for a xaa warning) as described in attached file 2; - at each startx (without system reboot), X registers a new display :0 :1 :2 :3 and so on. It never falls back to :0 unless I tell it manually to do so: startx -- :0 - so at this time, for both machines the attached file 2 is "/var/log/Xorg.10.log" (last X session); - startx says "Unknown boardID[000000ff], assuming FFB2, DoubleRES, Z-buffer, Single-buffered."; - dmesg is shown in attached file 3; - GUI starts, as confirmed by ps aux; - Screen becomes white, the previous black text becomes yellow. Window manager (wmaker) is running; - if creator0 kernel flag is set to 1 (disable accel), some blue dots appear instead of yellow text, but still no graphics; - I tried both default, 28.636 and 29.5 "Option" "ReferenceClock" according to xorg.conf manual - Xorg.0.log reports this option is never used; - if I start X11vnc, I can get a vnc client connection but the screen is white - so I suspect there is some wrong memory mapping: sunffb is using some bogus memory location while x11vnc is reading from somewhere else. Did anyone encounter this problem? Please advise.

MOS MCS2529 math chip

by fgueissaz59＠gmail.com

Hi Jules, Still interested to find out about powering the Melcor SC-635? I got one and succeeded to power it from 2.2 to 3.0V There is a switching regulator on the PCB (AS1930 from Astec International) that generates negative voltages (as referred to the negative side of the battery: -12.4V , -4.8V , and -2.0V At 2.4V, the current drain varies from 71mA (idle mode) to 185mA (all LED segments lit). For some strange reason, this current rises to 211mA when the C/CE key is pressed I will design a substitute power supply based on a single Li-ion battery with step-down regulator to deliver 2.4V Best regards Francois

Sun/3-powered 737 flight sim

by brendan＠bslabs.net

Something that I thought the folks here would appreciate: a fellow in Dubai is trying to keep a full-motion Boeing 737-300 sim (from 1991) running. The main host machine is a Sun/3E, connected over Ethernet to the operator workstation which has 2 Sun/3Es each with a cgtwo powering a CRT touch screen. One of the Sun VME SCSI/Ethernet boards died, and he?s been unable to find a (working) replacement board. There?s also a big rack of Concurrent hardware running OS/32, and some newer PCs for visuals and TCAS. Plenty of pictures and a video tour of all the hardware at: <https://www.reddit.com/r/BSD/comments/i8c8u7/how_do_i_emulate_a_sun_3e_comp… <https://www.reddit.com/r/BSD/comments/i8c8u7/how_do_i_emulate_a_sun_3e_comp…>> Brendan

Looking for a Stride OS set

by jos.dreesen＠greenmail.ch

I currently have 3 Stride 420 boards in various state of repair, one presumably fully functional,? and would need an OS set for these. Anyone have actual floppies or IMD images of either ucsd.p or Liason OS for these machines, or even just CP/M 68K ? There are disk iimages under the header "Stride"? on the web and Bitsavers,? but these are actually for the previous generation machines ( Sage II and IV) Jos

LA / SoCal area SDS branded (Sigma S7) Teletype Model 35 Avail.

by billdegnan＠gmail.com

Looking for someone in the LA area who knows how to properly pack and a few ship vintage items to be mailed to me. A computer, monitor and parts. The seller is not experienced in this and as a result the first thing that I got from him (A Model 33 Teletype top) was trashed. I don't want the stress of explaining or worrying about the next batch of stuff. So I turn to you, the vintage computing community to help. You get: Teletype Model 35 that I am told is in very nice shape. I'd love to take it myself but shipping is too expensive and difficult. The Pedestal is branded SDS, as in the old Sigma S7 computer. Xerox bought them out and sold the Sigma afterwards. That would date the Teletype in the late 60's or so. This would be a nice museum piece. I am told the Model 35 is practically unused. I get You pack and ship properly (you supply boxes and bubble wrap) a late 70's business PC, display terminal, and a TTY Model 33 pedestal (I already have the TTY itself). I anticipate the computer will be heavy and delicate and will need to be partially disassembled to add a little padding to the inside and to intelligently check out what you're dealing with. I am experienced in shipping this kind of stuff, and if it was me, I would expect it to take someone in LA area three or four hours to get the materials at the store, box, disassemble/sure up, pack, go to the post office, ship etc. I want it mailed USPS as I live in a rural area and they're the best here. This is the community, do I have a taker? If so contact me privately through https://www.vintagecomputer.net/contact.cfm. My timeline is next two weeks if possible. Thanks BIll Degnan kennettclassic.com vintagecomputer.net P.S. I will likely have a line to more cool stuff in LA area from this guy. You might want to check out what else he has, that in and of itself might make this venture worth it.

DEC VRE01 terminal documentation

by woolfson＠telswitch.com

Here's a photo of one of the restored PLATO terminals (which had the plasma display) Does the power supply for the PLASMA look like the one in this photo of one of the terminals with the covers off? ----- Original Message ----- From: Aaron Woolfson To: paulkoning at comcast.net ; uban at ubanproductions.com ; cctalk at classiccmp.org Sent: Thursday, August 13, 2020 1:50 PM Subject: Re: DEC VRE01 terminal documentation Hi Tom. Thanks for your message. Well, the Plasma panels use a pretty unique. I'm attaching the precise waveforms that the Plasma Panel expects to see in order to achieve the illumination of the dot. And while this may not be exactly or precisely what you're looking for, this will explain much about the technology involved. The fact that you can see any illumination at all is perhaps the most important part - beacuse the gas is probably there, and the "actuation" voltage might just not be high enough, or the sustainer voltage might have an issue. The power supplies were manufactured by Electro Plasma and were typically separate from the actual unit itself. I am going to see whether I can find the schematics for those power supplies, which discuss the characteristics . Also, check to see whether the back of the plasma panel itself has an edge connector that is similar to the attached TYCO specified connector. That might give you some insights into where to go. When I gave all my equipment and test gear to the LCM up in Seattle, I am pretty sure that they also got a lot of the original manuals and notes that had been hand written. But I typically had scans of most everything. I will see what I can find.... ----- Original Message ----- Subject: Re: DEC VRE01 terminal documentation Date: Thu, 13 Aug 2020 16:38:39 -0400 From: Paul Koning <paulkoning at comcast.net> You may want to see if the PLATO terminal documentation is any help, look on Bitsavers under University of Illinois. Those plasma display power supplies are hairy devices; the panel is actually a memory device and the power supply produces a high voltage AC waveform to make that work. Those panels normally light up around the rim; the fact you see that briefly but not sustained gives some hope that adjusting may be all that is needed. That's quite a display; the usual plasma panels were 8 inches square, 512 by 512 pixels. I'm guessing this is a 1k by 1k pixel display, which I have seen once or twice, at SAI in San Diego in some military displays. I know a plasma terminal expert; I've forwarded your message to him. paul > On Aug 13, 2020, at 3:23 PM, Tom Uban via cctalk <cctalk at classiccmp.org> wrote: > > I have a DEC VRE01 terminal that I bought NIB years ago.

Circuit board trace repair...

by wh.sudbrink＠verizon.net

Hi All, I'm going to be attempting to repair, both cosmetically and operationally, a circuit board that had a strip of 12 volt trace "blown off" of it by a short. The fiberglass is clean and there was no solder resist in the affected area. I'm considering using 3M 1183 adhesive tinned foil tape for the job. Has anyone else done this? Could you recommend this or another product? Any tips? Thanks, Bill Sudbrink -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

I found/scanned/OCR'd the "Technical data" flyer for HP-UX 7.0 (from 1989). It's at: http://www.sieler.com/hp/other/hp_ux_7_0.html Shortly after this, HP quietly dropped the "real time" portion of HP-UX, and in later years no one at HP seemed to know it had ever been there. Stan

Altair 8800 reproduction

by gregory.beat＠gmail.com

?Tom, Grant moved shortly after this Kit offering, over a decade ago. That kit is OVER (Grant no longer offering). Participate in the S100computers Group: http://www.s100computers.com/ Join the List at Google Group: S100Computers https://groups.google.com Grant special ordered the metal fabrication, at that time, from the original metal fabricators (Optima, $$), who have gone thru mergers & off-shoring. Mike Douglas looked into that chassis possibility ? but was cost prohibitive (>$300). Mike Douglas offers BOTH the Altair Clone (you referenced) AND the Altair 8800c Kits (November 2018). This case he had fabricated is a close look-a-like, but Lighter in weight. Still the case alone is $300 . This case does not have the internal Optima sub chassis (weight) and rails. ?https://deramp.com/altair_8800c.html Suggest you look at Mike?s multiple vintage computer offerings (web site) AND https://deramp.com/ His YouTube Videos (deramp5113). Here is the Altair 8800c, shown November 2018 https://youtu.be/Q5LjkL5b4n8 greg w9gb == From: Tom Hunter <ccth6600 at gmail.com> To: "General Discussion? <cctalk at classiccmp.org> Subject: Altair 8800 reproduction About 10 years ago Grant Stockly in Anchorage Alaska produced high quality MITS Altair 8800 reproductions in kit form. The website still exists: http://www.altairkit.com/ I have tried to contact Grant but did not get a reply. Does anyone know if these kits are still available? Is Grant on this forum? Alternatively is somebody else making complete Altair 8800 kits? I have found people making individual boards but not a complete kit. There is also the Altair 8800 clone which is based on a PIC microcontroller emulating the entire original Altair 8800. It is cute but not the real thing. Thanks Tom Hunter Sent from iPad Air

LSI-11 Simulator from Bob Meister

by rich.cini＠gmail.com

All ? ??????????????? I?m cleaning out my shop (I?m swimming in stuff so I will be creating a ?to go? list at some point), and this week I was going through boxes of magazine articles I saved. One is an article by Bob Meister that appeared in the July 1996 issue of Circuit Cellar with an LSI-11 simulator program. I was able to locate the C-source and get it to compile properly after some tweaking. ??????????????? The article says that he had to create a custom RT-11 driver for it, and it implies that it can use an image of an diskette, but it really doesn?t say what kind (assuming RX01). I wanted to pose this to the group to see if anyone ever heard of this program, used it, or otherwise knows Bob (email address in the article is no longer valid) so I can try to fill in the blanks a bit. Thanks! Rich -- Rich Cini http://www.classiccmp.org/cini http://www.classiccmp.org/altair32

HMS Victory "afloat" again on high-tech, hull-protecting supports

Virtual VCF Midwest!

by silent700＠gmail.com

So we're all stuck inside with no fabulous midwestern computer festivals to go to, so let's try to do this thing online. You produce the videos, we'll show them on the VCFMW Youtube channel using their "Premiere" feature to create a full day of classic computing presentations, along with a live chat with the creators (that's you) on YouTube as well as an all-day open chat on Discord/IRC. If you've got an idea for a video (criteria: on-topic, low noise), email us before September 1 (the sooner the better!) at virtual at vcfmw.org with: - How you?d like to be credited (real name or alias ok) - A one-line title/topic for your video - A short paragraph as an Abstract (plaintext, but can include URLs) - What time of day (morning, afternoon, or evening) you?d prefer your video shown If accepted, completed videos are due to us by Noon on Monday, September 7th. You can get your video to us in one of three ways: - Provide a download link for us to pick it up (FTP, dropbox, mega.nz, uucp, fidonet, etc.) - Upload via anonymous FTP to ftp.oldskool.org in the /incoming directory - If you have no edit capability and would like to stream directly to Youtube from your phone or tablet, go ahead and do so, making your video ?Unlisted?, then email us the link and we?ll pick it up. Be sure to include some or all of the filename in your email so that we match videos up with the right people. The full linkable announcements are here: https://mailchi.mp/1f03fef220b3/vcf-midwest-15-virtual-event? http://vcfmw.org/virtual.html -j

Unix text processing software with daisy wheel output

by chris＠groessler.org

Hi, I want to use my daisy wheel printer to create letters and memos and similar (rather simple) texts. What can I use to write the text? I think "special effects" with daisy wheel printers are "bold" and "underline" parts. And "double stroke" (if that's the correct word, I mean a space char between each char). groff (or any *roff) comes to my mind. Are there other options? regards, chris

DEC Server 300

by dj.taylor4＠comcast.net

I'm interested in getting one of these, but browsing the manuals it appears there is software that is installed on the VAX to use them with VMS. Is the software required to attach terminals and login to various Vax's?? Or is it for management of the Dec Server 300? If the software is required, where do I find it?? Is it in the hobbyist distribution?? Is there a VAX and ALPHA version? Doug

DEC VR260 service docs / common failure modes?

by derschjo＠gmail.com

Hi all -- Picked up a non-functional but otherwise nice looking DEC VR260 (19" b&w monitor) on the cheap, hoping to use it with my VAXstation 2000. From what I've read, these were never the most reliable displays. Curious if anyone has any information on common failure modes, or has service docs squirreled away somewhere. I've at least found schematics, so I have something to go on, but it's not exactly the most straightforward design I've poked at. Right now when powered up I hear a repeated low hum from the transformer followed by a soft ticking noise so I'm guessing I've got power supply issues at the very least. Unsure what I should expect the monitor to do if it's not being fed a valid video signal (I haven't yet tried to hook the VS2000 up to it) -- whether it'll go into free-running mode or do mostly nothing until it has something to sync to... Thanks as always, Josh

Acer-Altos System 4500

by marco＠familie-rauhut.eu

Hi List I have here a Acer-Altos System 4500. It is a 486/33 EISA System with an Altos Basic SCSI Bsc(e) Controller. It has an Altos Multidrop/2 EISA Controller (to controll TCU Boxes that handle RS232 Ports) and a VGA1024i EISA Graphics controller. My mision is to bring that System back to life respectively get access to the Discs. The built in SCSI Disk are running and i have created Images of this Disks in a Linux PC. But i can not boot the System by one of this Disks. I remember that on this disk is some sort of Altos SCO Unix System V installed. Did sombody here on the list have documentation or the original Installationmedia (QIC-525) for that system? Marco

Burroughs L-series paper tapes

by sieler＠allegro.com

> > Mike Stein writes: > > I remember there was another L9000 rescued in California years ago, > but maybe that's the one you have now. > My consulting company was in Redwood City, CA. Our nextdoor neighbor had a company leasing new cars. They ran the company on a Burroughs L9000. About August of 2000, they were at the point where they could no longer obtain ledger cards (roughly 8x11 with a magnetic stripe down the side for computer data), for the L9000, so they were going to move to a PC-based system. The owner knew I was a computer collector, so he offered to give me the L9000. I was tempted...but it was a large machine, so I arranged for it to be given to the Computer History Museum (where I was, or became (timeline hazy) a senior docent). I remember the owner saying that only the cleverness of their independent maintenance guy had kept the machine running ... to the point where he'd machined some replacement parts himself. I talked to the elderly lady who ran the machine (i.e., did the data entry). She compared it to the PC, and lamented the loss of the L9000. The L9000 was so much faster and easier to use! She could probably enter data four or five times faster on the L9000. It wasn't just a matter of familiarity ... much of the slowdown was due to the GUI nature of the PC program they switched to, and they no longer had the luxury of having relatively purpose-related hardware on the L9000.

I've bought a small number of L-series tapes over the years that I finally read yesterday, mostly pass 1 and 2 of the assembler. Part numbers look like this. Oddly, they all seem to be wound backwards. The person-readable label is at the end, which will make it annoying to scan. 1-2101-049-01 1-2101-052-07 1-1001-008-07 1-1001-009-07 Anyone have any others?

A tale of two Automated Logic Diagram Sheets

by cube1＠charter.net

I encountered my second missing Automated Logic Diagram (ALD) page for the IBM 1410: 13.64.03.1, which, based on the signals fed to it and which it produces, would, fortunately, necessarily have the same logic as page 15.41.10.1 - "E CH FULL CONTROL-ACC". Page 13.64.03.1 is for the second, or F Channel. The E Channel version uses 9 NAND gates and 4 drivers. However, based on the card location chart, the F Channel version, even though it would have corresponding logic, has TWENTY-ONE gates (some of those could be just load resistors) on card type DGR. These are ALL just INVERTERS. The card location chart also calls out 2 gates on card type DFS - also inverters, and one gate on card type AEK which uses equation (NOT IN1) OR IN2 to produce its output. The F channel logic used up two cards slots plus parts of six others. The E Channel logic version used three card slots (probably in their entirety) and the drivers used parts of four other cards slots What to do? As readers will likely know, you can't do any real logic with just inverters. However, SMS card outputs can be hooked together with all but one of the gates so connected (or "DOT-ed") having open collector outputs. Electrically, given the circuits on the DGR and DFS cards (as well as most others the IBM 1410 uses), if you follow that with an inverter you get OR => NOT, aka "NOR" logic. Now that we can do something with. So, I wrote a VHDL test bench, based on the Intermediate Logic Diagram (ILD) that shows the necessary logic for the E Channel (and indicates the F Channel is the same), and tested that against the E Channel page to make sure my understanding of the logic was correct. Then, as an exercise, with liberal application of DeMorgan's theorems, I proceeded to lay out the logic for the F channel version in that fashion. It took 21 inverters (using the AEK as an inverter) and 1 load resistor (which I probably didn't need to use) and eight DOT functions (ORs) to produce the necessary logic. So, pretty close, but not a perfect reproduction. One thing is an issue for sure: I "DOT-ed" two inputs together that come from other sheets whose outputs are used on still other sheets - which is generally a no-no. It would not have been that way on the original machine - they would need to be isolated by being fed into gates of some sort - even if only back to back inverters. I could probably spend a bit more time, find a way to leverage the second input on the gate AEK, and get it more exact, but frankly, it isn't worth the effort right now. JRJ ?

Seeking PET 4016/32 'shift' keycap

by jules.richardson99＠gmail.com

After over a decade of keeping eyes peeled, I found a Commodore PET 4016 at a yard sale yesterday (it actually wasn't in the sale, but there was some old phone stuff there, and when I see anything like that I always ask the owner if they happen to have any vintage computer stuff hiding away). The case is pretty battered, and it was disgusting and reeked of rodent urine, but after cleaning it and going over things it (incredibly) actually works. I am, however, missing a right shift keycap. Does anyone happen to have a junker (perhaps one that's already missing keys) and so would be willing to sell me one? It's identical to the left-side, and I think is shared with the 4032 models. Cosmetically the machine's never going to be perfect (at least not without some careful gluing on a couple of cracks and a full repaint), but a complete keyboard would improve things considerably! thanks Jules

Any interest in "newer" hardware, software?

by boris＠summitclinic.com

Have been going through my shop and storage room trying to see what can get rid of and wasn't aware of how much old electronics and computers have accumulated over last 50 years. Should note that this process has been at insistance of my wife as a lot of these boxes just got moved whenever I moved and much of this stuff haven't looked at for decades. Was about to toss a 1987 box containing DOS 3.3 but then figured someone might want it. Have a couple of XT systems kicking around somewhere but in 1987 I'd discovered the Mac and considered 68000 processor a far superior architecture as it was an easy transition >from someone who'd spent most of their time programming on a PDP-11. Also have early Mac software, hundreds of 3.5" disks which are primarily taking up space and all of them have been copied to HDD's and now run my Mac code under Basilisk2 was faster than it used to run on my MacIIvx (of which I have a couple). Also managed to find, in no particular order, a couple of C64's, a TI99, ZX81, VIC20 and an 8" floppy drive with full documentation that I faintly recall buying at a surplus electronics place in Seattle. Also found a box of old Univac cards which appear to be DTL with individual transistors and then go on to having DTL IC's as well as some old IBM cards. Used to pull transistors and diodes off these to build my own circuits 50 years ago. Now, with storage being so ridiculously cheap haven't even come close to making a dent in the capacity of a 256 Gb SD card in my Samsung S8 handheld supercomputer of which I'm using the camera function to create high res images of what I'm going through. Also have lots of PC motherboards starting with XT's and progressing upwards. Never liked 80286 and so only collected from 80386 and higher. Seem to have lots of various parallel port adapters, disk interfaces as well as parallel and serial port boards. Was planning on using these as dedicated processors for data acquisition but found that technology progressed faster than my getting around to use them and it's a lot simpler to either use Phidget's SBC with various sensors for environmental monitoring or a much less power hungry Parallax Propellar chip for more demanding data acquisition applications. (Haven't let my wife know how many of newer systems I have stashed away but they take up way less room than old hardware). Do also have a couple of PDP 11/23 systems which I'll probably have to part with as I haven't used then in last 15 years. Also have a number of unibus boards which haven't run into yet but won't be using them. Lots of old computer books as well which would be nice to keep but likely have most of documentation in digital form and usually back up all important pdf files to separate drives. The PC stuff is most voluminous and, if there's any interest, can post images of what I have on my web site. Only components I've tested are disk drives of which most work but SCSI drives are all old and a number of them didn't take kindly to be powered off after running for years and being moved from Vancouver to Kamloops.

Tallgrass PC hardfile driver/utility software

by bear＠typewritten.org

Folks; I see (and am grateful for) the disk images for the Tallgrass PC Hardfile/Tape unit (TG 3000/3100 series, such as my TG-3020) that have been archived on minuszerodegrees.com. This represents version 4.xx of the utilties, for use with PC-DOS 2.x. I was hoping to use this device on a 5150 PC with PC-DOS 1.1 and CP/M-86. This requires an older version (3.xx) of the DOS software, and one for CP/M-86 1.00 (also Tallgrass software version 3.xx? but a separate disk, I should imagine). If anybody happens to have a copy of either of these and don't mind sharing it, I'd love to hear from you. Thanks! ok bear. -- until further notice

Teletype KSR 33 in portable hard-shell case

by jfoust＠threedee.com

I'd like to know what to call this portable teletype 33. I have not yet found any ID tag. I'd love to see some original literature. Have not yet found another on the internets. The hard-shell lid is removable and has a nice compartment to hold the DA-15 to DB-25 serial cable and the AC power cable. I uploaded pics at https://imgur.com/a/zAHchbb . It has some issues. Typing JOHN FOUST gives HMHL DMEAD and line feed doesn't. - John

Monitors FTGH

by a.carlini＠ntlworld.com

The following four monitors are available free for pickup in the UK (OX17 postcode). All appear clean but are untested. All are believed to have been functional when stored but that was ~2002/2003-ish. Microvitec Cub. Seems to be in its original box. DEC VRT19-D3. Vision Master Pro 17. DEC VRC21-W3. Obviously with the current restrictions on movement these cannot be picked up, but they need to be gone soon after the restrictions are over. Expressions of interest offlist please.

I have an old Dell Precision T3400, but its BIOS will only allow 1.2MB 5.25 floppies. The version from the Maslin Archive and both my original Otrona MS-DOS 2.11d disks (from 1983) and the MS-DOS-2.11 2.11e disks that I downloaded from FAUG after Otrona went out of business do not include Assign or Subst. However, the 2.11e disk includes support for a hard drive, so I believe that it can handle a C: drive. I received a copy of Assign from MS-DOS 2.1 from another list member, so I have asked him if he can copy it to a floppy that I can send him. Bob

paper tape archiving

by guykd＠optusnet.com.au

Be glad you don't have to deal with this kind of thing: http://everist.org/pics/misc/20200719_6831_wet_tapes.jpg A bunch of PDP 8 system tapes. That were literally soaking in liquid water when recovered. Yes, that is mildew. They are nearly dried out now. Still to be determined if they can be manually teased apart intact enough to be read. After deciphering what they all are, from remnants of the labels and a paper list that was with them. Hopefully these are already online somewhere. If not, then a lot of work to recover. The DEC mag tapes... sigh. Still not even thinking about them. Just slow drying. Guy

OS-9/68k Control Coprocessor module

by chd＠chdickman.com

I came across an Allen-Bradley 1771-DMC4 Control Coprocessor. If you are familiar with AB PLC's, it is a 1771-IO chassis module that could be a "sidecar" for a PLC5 PLC or a standalone module. It runs some version of OS-9/68k on a 68340 processor. It has 4MB static ram and a 10MB ethernet AUI connector. I hooked up a terminal and can get to an OS-9 prompt. It has by default a 64k RAM disk that is empty. The best I can gather is that there was an external IDE (AB 1771-PCB PCbridge) that was used to create programs that were loaded onto the RAM disk. Once configured it would run standalone. Microware is still around in some form so OS-9 is not completely dead and I did find some references to a Microware product called PBbridge. It would be interesting to experiment with. I am curious if anyone has any experience with this hardware, with the IDE or OS-9/68k in general. I've never seen much discussion of OS-9/68k on classicmp.

paper tape archiving

by billdegnan＠gmail.com

Hi all. I was wondering if there are any good online resources on reading for the purpose of archiving 8-bit papertapes of unknown origin. I have been reading tapes as text and also as binary, 8/n/1 thinking that's going to capture everything. I load into a hex editor, and if necessary convert to octal. I am wondering if there any persons who have a systematic process they'd like to share for this kind of work. I will share the tapes I have with the community, but there is no point if I am not doing it right. Thanks Bill

Comp.lang.forth: banned on google groups?

by dfnr2＠yahoo.com

I was looking for an old post on comp.lang.forth, and was surprised to discover that the group doesn't appear to be hosted on google groups any more.? Searching the group pulls up a "banned group" message, and selecting the "continue to the group" button shows 0 messages in the group.? This appears to be due to spam showing up in the unmoderated group. Google bought Dejanews years ago, and, as I understand, was the defacto main usenet repository.? Is is all really gone, or just temporarily hidden?? How long ago did this happen?? Is the full comp.lang.forth archive available anywhere? ? I wonder if it's time to set up some NNTP mirrors and gather as much historical usenet content as possible.? Much of the overall content is garbage, but there's some priceless stuff in there, and even more that will become interesting in light of future developments. Dave

Morrow MD3 terminal emulation.

by technoid6502＠gmail.com

TRS 80 Model 12 Picked up

by lyokoboy0＠gmail.com

Greetings. It has been an interesting day. Rather late in the day, a buddy notified me of a local thrift store that went under, and mentioned there may be some computers on site up for grabs. Upon arrival, the place was a mess, but the folks there were friendly and gave me the tour, everything had to go, the shopkeeper skipped town and left the place full of junk for the Building owner to clean out. I found a TRS 80 Model 12, a vga commodore branded monitor, commodore cassette drive, among some misc 5.25 floppy disks. There may be more, I need to go back for another sweep in the morning. The computer is extremely big, taking up an entire kitchen table,rivaling the space that is taken up on my desk for a pdp 11. I am looking to clear a space to work on it without dropping parts. The machine looks to be clean, However i am missing the keyboard. The machine does not power on or show anything on the screen. I do hear a high pitched hiss, so there may be some kind of power supply issue. I was not aware of this model of machine, I am curious if anyone has a spare keyboard for sale. I am not familiar with this model, it has 2, 8 inch floppy drives on the front. I am curious about the format of the disks, would it be possible to use another computer with an 8 inch drive to make a floppy to start the machine, or do the drives use an odd difficult format that would be impossible to write? http://devindamico.com/Uploads/TRS80M12.jpg --Devin D.

MS-DOS 2.11 Assign.com

by r_a_feldman＠hotmail.com

I'm trying to copy files off my Otrona Attache 8:16 using FastLynx 3.3, but I keep getting an error 708 when trying to push SL.EXE to the Otrona over the serial port. I am wondering if the reason for the error is that the Otrona does not have a C: drive. Therefore, I would like to try to use Assign.com to assign C: to A:, but the Attache version of MS-DOS 2.11 does not include Assign.com. Does anyone have a copy of the MS-DOS 2.11 version of Assign.com they can send me? Thanks, Robert Feldman

CLCC68 Covers

by pbirkel＠gmail.com

I intend to restore a pair of boards that used Intel Ceramic Leadless Chip Carrier (CLCC) parts. Unfortunately the socket covers were tossed when the boards were scavenged for their chips. The sockets and attached clips are themselves just fine. eBay item # 252830664338 is an example of this style of 68-pin socket. Item # 362702811275 is an example IC in CLCC form. If anyone has a par (or even just one) of these covers lurking in their odds-n-ends collection somewhere I'm interested in putting them back into service. Thank you for taking a look! paul

chaos and the LGP-30

by wrcooke＠wrcooke.net

The LGP-30 has been discussed here (often fondly) a few times so I thought this might be of interest. Adds a bit of fame to the little guy that I wasn't aware of. I was reading the wikipedia web page on chaos theory and found this passage: "Edward Lorenz was an early pioneer of the theory. His interest in chaos came about accidentally through his work on weather prediction in 1961.[12] Lorenz was using a simple digital computer, a Royal McBee LGP-30, to run his weather simulation. He wanted to see a sequence of data again, and to save time he started the simulation in the middle of its course. He did this by entering a printout of the data that corresponded to conditions in the middle of the original simulation. To his surprise, the weather the machine began to predict was completely different from the previous calculation. " https://en.wikipedia.org/wiki/Chaos_theory#History Will

Any interest in "newer" hardware, software?

by boris＠summitclinic.com

Mike: Just looked in more detail at photographs of my notes in drive box and appears I did verify that drive motor worked in 1987. Project to get this drive connected to my C64 got derailed by my being accepted to medical school a couple of months after my last interaction with that drive. Was somewhat surprised to discover that 8" floppy drive as I thought the Vic20 box had my other TI99 computer which might have been lost at some point in last 30 years and multiple moves. Never had a chance to try reading an 8" PDP-11 floppy in it and no longer have any as all of them went to Glen Slick in 2008 when he got my MINC and related hardware. There was an interesting computer surplus store in Seattle that I no longer recall name of, but one of landmarks was a company that sold Buffalo Wipes nearby. Unfortunately places like this no longer exist and remember it being crammed full of various bits of electronics that would have to be lifted out of way to see what was buried underneath. Easy to spend a day in there poking around. Everything was as-is and often just good for parts. Location you've specified as a means of transferring drive a good one and a short drive >from Kamloops and one I like doing but unfortunately limited to Canadian side of border now. Did run across a couple of 80486 boards today and must have played with them as found some 80 Mb HDD's in same box. One was fully loaded with about 8 Mb of RAM!

Altair 8800 reproduction

by stephen.m.pereira.sr＠gmail.com

I had the same confusion about Mike?s Altair 8800c not being a complete kit, and wondering what it would take to ?upgrade? my Altair 8800 Clone to be a real Altair 8800c a bit more than a year ago. I ended up not finding very much assistance at the time, so I bulled my way through it, and got it done using the info and pointers from Mike?s site. Another time someone asked about this I posted my experience on the VCF. See this: http://www.vcfed.org/forum/showthread.php?69929-Altair-8800-clone-cost-to-b… <http://www.vcfed.org/forum/showthread.php?69929-Altair-8800-clone-cost-to-b…> Mike?s original topic on VCF is here: http://www.vcfed.org/forum/showthread.php?66737-Building-and-Altair-8800-fr… The bottom line is that you *can* get it done with the info and pointers that Mike provides on his site. He is also reachable on the VCF and also by telephone. He is tremendously helpful and will answer any questions that you may have. smp - - - Stephen Pereira Bedford, NH 03110 KB1SXE > On Jul 24, 2020, at 1:00 PM, cctech-request at classiccmp.org wrote: > > > Message: 13 > Date: Fri, 24 Jul 2020 11:15:34 +0800 > From: Tom Hunter <ccth6600 at gmail.com> > To: Greg Beat <gregory.beat at gmail.com> > Cc: "General Discussion: On-Topic and Off-Topic Posts" > <cctalk at classiccmp.org> > Subject: Re: Altair 8800 reproduction > Message-ID: > <CAALEduAsERN897fBN8rDCqt_mN6wHc2J8qSDzYyhfU2CibmiJQ at mail.gmail.com> > Content-Type: text/plain; charset="UTF-8" > > Hi Greg, > > I saw Mike Douglas' Altair 8800c but he writes on his website that this is > not a complete kit.

IBM 3194 VDU (WTB/pinout).

by andrew＠carrierdetect.com

I have an IBM 3194 base unit and keyboard, but no monitor. Hence would like to try and source a suitable monitor and any suggestions on this front would be appreciated. Failing which, also considering the possibility of using some other non-original monitor, but not sure what the interface (15-pin D type, but standard density) is and pinout etc. Also potentially interested in offers of other 3270 displays (off-list). Cheers, Andrew

cctalk Digest, Vol 70, Issue 22

by athornton＠gmail.com

If it's actually running on real z hardware Linux is probably already running under z/VM. If it's running on Hercules, then....OK, but the host system could have handled the Infocom games without ever even blinking. But I've been known to do silly emulation tricks too: https://www.fsf.net/~adam/NT-on-390-desktop.png Adam On Thu, Jul 23, 2020 at 10:00 AM <cctalk-request at classiccmp.org> wrote: > Send cctalk mailing list submissions to > cctalk at classiccmp.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://www.classiccmp.org/mailman/listinfo/cctalk > or, via email, send a message with subject or body 'help' to > cctalk-request at classiccmp.org > > You can reach the person managing the list at > cctalk-owner at classiccmp.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of cctalk digest..." > > > Today's Topics: > > 1.

Altair 8800 reproduction

by ccth6600＠gmail.com

About 10 years ago Grant Stockly in Anchorage Alaska produced high quality MITS Altair 8800 reproductions in kit form. The website still exists: http://www.altairkit.com/ I have tried to contact Grant but did not get a reply. Does anyone know if these kits are still available? Is Grant on this forum? Alternatively is somebody else making complete Altair 8800 kits? I have found people making individual boards but not a complete kit. There is also the Altair 8800 clone which is based on a PIC microcontroller emulating the entire original Altair 8800. It is cute but not the real thing. Thanks Tom Hunter

Getting files off a 7300

by cz＠alembic.crystel.com

Anyone know the best way to get files off an AT&T 7300/3B1 computer? This one has a lot of Perq stuff in a directory as well as hilarious things you can do with RP06 disk platters (ah, when we were young...) It does have an AUI Ethernet port on the back, but doesn't appear to have TCP/IP installed. Maybe I can install TCP and find my old Synoptics 10bt to AUI adapter? CZ

HP3000 Microcode is in SYSDUMP (backup) for WCS machines (64,68,70, 37,...)

by rdbrown0au＠gmail.com

If written on a Series 64, 68 or 70, or on the Series 37 or it's successors, the first file on a SYSDUMP (Backup) tape may include the Microcode from the WCS (Writeable Control Store). Please collect such files if you have tapes available that you can read. Note that the first file includes a concatenation of system objects, ending with (optionally) the directory so that may leak data that should remain private. It's possible that the distribution tape for MPE V Release 3P G.40 that the HP Computer Museum has http://www.hpmuseum.net/display_item.php?sw=442 might also include the WCS data. The bootable disc image for the Series 37 and it's successors will. The Museum website doesn't mention media for their 68. Thanks as always to Al Kossow for his BitSavers work. 30140-90045_Series_64_68_70_Microcode_Manual_Oct86.pdf has a 543 page listing of the microcode assembly output, which should wait for better OCR software.

Looking for copy of BASIC ROM for HP 3396B Integrator II

by Martin.Hepperle＠dlr.de

Recently, I obtained a HP 3396B Integrator II. This is a device for the chemical analysis laboratory. I had hoped that this device contained a BASIC interpreter, but this was not the case. Through the serial interface I can connect a terminal program. Pressing CTRL+BREAK outputs the sign-on message serial interface: ~~HP3396,IBLI Unfortunately, typing "BX" for "Basic eXternal" on the keyboard tells me: BASIC NOT INSTALLED So I am wondering, whether I can install a BASIC by replacing the ROM with an EPROM. According to the "Installation and Service Manual", the ROM U 110 came in two versions: Z-80 Standard-ROM 03396-80012 Z-80 BASIC-ROM 03396-80032 This means that the BASIC is NOT in the cradled EPROM but in the ROM in the lower right corner of the PCB. My ROM 80013 is probably an revision of 80012. So: I need a copy of the 03396-80032 ROM chip. Additionally, if someone has the manual "RS232 Programming Manual", P/N 03396-90335", for the 3396 integrator. it would be great if he could scan the document and make the content available. [I have the remaining manuals and already sent scans to the HP Museum in Australia for making them available o their site. Main PCB: +----------------+ +----------------+ | PPP EPROM | | U 111 | | 27C011-200V10 | | 27C010-150V10 | | 03396-80106 | | 03396-80023 | +----------------+ +----------------+ +----------------+ +----------------+ | U 317 | | U 110 | | 27128A | | ROM | | 03396-80043 | | 03396-80013 | +----------------+ +----------------+ Opening the Case - remove transparent cover from printer compartment by pressing the hinge flaps inside - remove 2 screws close to rear edge, from top - remove 2 screws in printer compartment from top - remove keyboard: - keyboard is "hinged" at the front with three rigid noses - use a pry tool to open the 3 latches at the rear edge of the keyboard plate - lift the rear edge and pull the plate back - if you are careful, the ribbon cable can stay in place, you can thread the keyboard plate through the case opening - lift case cover upwards Thank you for reading, Martin

Compaq Smart Array 3200 Controller as a SCSI Controller

This may be a bit too new for this list but I thought what the heck - maybe one of you Compaq/DEC/HP guys would know: Is there any reason a Smart Array controller can't be used as a simple SCSI controller? I.E. No array, just using it to drive a tape library? TIA! -Ali

Sun E250, NVRAM edit? (Serial Speeds, no console, etc)

by silvercreekvalley＠yahoo.com

Hi Ethan In theory console can be set to anything but its usually 9600/8/n/1 as I?m sure you?ve tried. On some suns unplugging the serial cable is the equivalent of sending a break, so might be worth a try? Suns do require full hardware signalling on the console connection so might be worth checking.

windows program to read papertape from reader through serial port

by billdegnan＠gmail.com

Hi - I read on teraterm's forum or something like it that teraterm is not really equipped to receive an inbound papertape reader dump into an ascii file. What do those of you who have both windows and a tape reader use? RealTerm? If so, what settings? I have been wresting with this for a while...I am told my DSI NC 2400 needs hardware flow control Thanks BIll

Fan problem with DEC H7822 power supply in MicroVAX 3100

by cctalk＠beyondthepale.ie

I have a MicroVAX 3100 which has a H7822 power supply. The power supply and the machine itself mostly work (there is a problem with the SCSI interfaces but that's another story) except that the two fans in the power supply don't run. If left on for a long time, the machine gets too hot and a thermal trip operates, shutting it down. The fans are DC 12V 0.2A and if I connect them to +5V or +12V, they work fine and don't draw excessive current so there would seem to be a problem with the section of the power supply which drives the fans. Unfortunately, it's operation is not obvious and the power supply is a pig to work on. It consists of two double sided PCBs connected by short leads and having live parts on both boards making it difficult to get access to both sides of the board where the fan circuit is when the power is on. I don't have an identical working power supply to compare the faulty one to but the fan circuit looks superficially similar to the one in the H7821 which I do have working examples of so that may be a way to proceed. Does anyone have a service manual for the H7822 or H7821 or know how the fan circuit is supposed to work in these power supplies? Regards, Peter Coghlan.

Anyone out there that can read 7 track / 556 BPI tapes?

by cramcram＠gmail.com

Hi, I bumped into an old friend of mine today. We both talked about a pair of machines we worked on that no longer exist as far as we cant tell. They were both Adage machines and had the same base digital architecture. Their names are Ambilog 200 and AGT-30. The Ambilog was the predecessor to the AGT line. The AGT came in 3 flavors, AGT-10, AGT-30 and AGT-50. The 30 seems to have been the most prevalent. They were 30 bit, one's complement machines. The Ambilog had a beautiful console that used an IO Selectric. It was designed as a 2D vector graphics machine. Here's an image of the Ambilog 200: Ambilog 200 <https://d.lib.ncsu.edu/collections/catalog/ua023_024-001-bx0010-020-004#?c=…> The AGT/30 was a very advanced 3D vector machine. The XYZ signals for the display came from a 4 x 3 "hybrid" matrix multiplier which allowed for 3D imaging with Z axis depth cueing. The matrix multiplier was a 19 in rack of a dozen discrete 15 bit multiplying D to A converters. About once a year it had to be re-calibrated due to long term drift. Here's a link to an image of an AGT-30: Adage AGT-30 <https://www.google.com/url?sa=i&url=http%3A%2F%2Fwhat-when-how.com%2FTutori…> And here is it's 1.5 seconds of fame from the SciFi classic "Dark Star": AGT-30 das Blinkenlights <https://youtu.be/ocse-0bBfo8?t=3152> Anyway, it turns out he has quite a few of the source and backup tapes. Unfortunately they are 7 track 556 BPI. So the question is: is there anyone out there that can assist with either reading these tapes or (better yet) has a 7 track tape head we could buy? Our goal is to preserve this forgotten machine designed at the start of the computer graphics era. Writing a full emulator is our goal. I live in the Bay Area. Maybe those of you with connections to CHM could see if we could read the tapes on the 1401. Or maybe one of you has a 7 track driver in your junk file. All we really would need is the head and we could put it on an existing drive. As a last option, a commercial tape recovery vendor although that is probably too pricey. Thanks, Marc Howard

Help identifying mystery Dataram VAX-11/750 (?) board

by derschjo＠gmail.com

Hi all -- Picked up a board advertised as a "4mb memory board" for a VAX-11/750. It's made by Dataram and I'm unsure of the model number, based on photos of it. I just noticed that rather than being a hex-height board that goes in the memory backplane, it looks like a board that goes in the main CMI backplane. It also appears to have 16mb of ECC memory on it, rather than 4mb. My thought is either (1) it's not actually for an 11/750 (in which case I'm curious what it would go into), or (2) it completely replaces the memory controller and standard memory and gives you 16mb in the 750. (Or it could be that it's something else entirely.) If anyone has any ideas or has a source of information, let me know. I put up a few pictures here: http://yahozna.dyndns.org/scratch/dataram/ Thanks as always, - Josh

Small C ver 1.00 source?

by wrcooke＠wrcooke.net

I'm trying to find source files for the very first, original, ver 1.00(?) small C compiler. I have the DDJ issue with the printed source (minus the assembly language runtime libs.) I have found all sorts of derivative works, but I haven't found files of the original version. My old eyes aren't up to typing in 13 pages of scanned copy of printed dot matrix listings. Does anyone know where a downloadable copy of these files can be found? Or have a copy they could send?

interfacing DSI NC 2400 tape reader/punch

by billdegnan＠gmail.com

Is there a trick to archiving tapes to PC using Teraterm from a DSI NC 2400 reader/punch? Or is there a best software for this? From the terminal I can ctrl+Q to cause the reader to initiate a read of a test tape but I can't capture the output of the tape through the modem port of the reader into the serial port of my PC. I tried various things with settings. I was told it uses hardware flow control. The reader is set correctly as far as I can tell. I am using 2400/8/n/1 but I have tried other settings. I get no response from the terminal inbound at all. I am using a USB to serial interface that I know works with an RS232 modem, but it may not work with the reader. If so, I'd like to know if anyone has a similar experience. It may not be straight forward and I have to make a custom cable. I will keep at it, report if I find the answers. Bill

Dilithium Press (Computer Books)

by healyzh＠avanthar.com

Out of curiosity, does anyone know anything about this publisher? They apparently existed in the late 70?s and early 80?s. They were apparently located in Beaverton, Oregon in the same business park, on Nimbus, where Norvac Electronics was. They obviously published some very strange computer books, including what looks to be a teen romance. I find myself with an embarrassingly nice little collection of the books, that my Dad apparently had. Considering I think he touched a computer twice in his life, they?re something of a mystery. Best title, ?Nailing Jelly to a Tree?, which is apparently a book on Software. The publisher sounds vaguely familiar, and I think I might have one or two other books from them in my collection. Zane

CDC CYBER 170 Consoles

by ccth6600＠gmail.com

I have been working on CDC CYBER 170 mainframes between 1977 and 1988. In 2002 I wrote an open-source emulator for the CDC 6000 and CYBER series (see my website http://www.control-data.info/). In 2013 I also developed the open-source VHDL firmware emulating the console controller for these systems. The firmware runs on a Xilinx Virtex 6 FPGA on a PCI Express (PCIe) board. The off-the shelf Xilinx board carries a small custom "piggy-back" board with 4 DACs and 4 op-amps to interface to a DD60or CC545 console. This PCIe board was used by Paul Allen's Living Computer Museum (LCM) in Seattle from 2013 onward in a PC running my 6000/CYBER series emulator to drive a real DD60 console. The CC545 has a very similar interface and my emulated controller would work with it too. For many years I have been trying to find one of these vector drawn CC545 consoles to use with my emulator but I haven't been able to find one. Recently I decided to build a clone of it myself. Bitsavers has a hardware manual with schematics: http://www.bitsavers.org/pdf/cdc/cyber/cyber_170/62952600L_CYBER_170_Displa… The CC545 console achieved unusually fast deflection with an electromagnetically deflected CRT. I am trying to understand the tricks they used to get these high speeds. Part of the magic is a dual-yoke which provided gross positioning within 2 microseconds to anywhere on the screen using the first yoke (this is VERY fast) and then painted the character using a second yoke around that base position with 0.1 microsecond per stroke (this is VERY fast too). The two yokes work in an additive manner. The reason there are two yokes is that you need quite low inductivity/impedance to be able to drive the symbol vectors at 0.1 microsecond per vector with up to 24 vectors making up one character. The gross position yoke needs to create a large enough magnetic field to sweep across the entire screen so has a higher inductivity/impedance but the magnetic field has 2 microseconds to stabilise. The older DD60 console used electrostatic deflection which is much faster by its very nature. Traditional CRT oscilloscopes were all electrostatically deflected because of the speed advantage over electromagnetic deflection. The CC545 manual on Bitsavers has a good description of the circuits and schematics, but unfortunately Section 8 with the "Parts Data" has not been scanned. I really would like to know the types of transistors used in the 4 deflection amplifiers as well as the details of the dual-yoke and possibly the CRT data. It would also be very useful to see details of the design of the dual-yoke and possibly the inductivity of each of the coils. This dual-yoke is most unusual and very different from what is used in TVs, CRT monitors and even vector drawn games like Vectrex or early vector drawn Atari arcade games. Could somebody please help? Thanks Tom Hunter

A tool many of you may make find useful!

by dave.dunfield＠gmail.com

Continuing to let you all know about developments, I do expect that many of you are facing a similar problem - trying to condense and preserve a lifetime of "collecting digital stuff". The DFF utility has been very helpful, however once I started organizing my files, I realized that although there are a lot of duplication, much of it is was downloaded at different times and/or from different sites making much of it different, many vendors don't go out of their way to make file content/purpose obvious in the names, and many files are dependent on other files - so manually reorganizing the data is NOT always easy. The best solution I have come up with so far is to invent a new archive format designed to eliminate duplicate data but capable of recreating the entire original directory trees (or parts thereof). To that end I created the two utilities described below (now included in the web archive). -- yeah, I do seem to have a fair bit of spare time on my hands these days... ;=BDA - Build Dave's Archive ;=EDA - Extract Dave's Archive Dave's Archives contain the smallest possible representation of a complete directory tree: - Only one copy of the data for duplicate files is stored. - Duplicate filenames are stored only once. - Path information is stored only once per directory, and only additions to a path are stored (adding/removing from last path). eg: Starting with a large DIR of support files for one of my systems. This has duplicates and a lot of pre-compressed install files: 314 dirs, 930 files using 3,762,691,033 bytes. Just "ZIP"ing it I get: SysSupt.zip 3,352,081,951 bytes 7zip does a bit better: SysSupt.7z 3,245,871,362 bytes Running BDA, I get: SysSupt.DA1 9,404 bytes and SysSupt.DA2 1,912,855,711 bytes Big improvement, but no compression yet, using ZIP and 7zip I get: SysSupt.zip 1,636,965,417 bytes and SysSupt.7z 1,609,663,862 bytes And YES, using ZIP/7zip to extract the .DA's, then EDA gives me a directory with exactly the same content that I started with. Like my other tools, these can deal with BIG directory trees, and the output file format is well documented should you ever want to recover the files by other means. Sorry if I've not responded to messages here, tend not to follow the list directly much these days due to the high content, but you can always reach me through the link on my site - might take me a few days to respond, but I do get to it from time to time...

TM848 repair?

by brain＠jbrain.com

Anyone on list repair or rehab Tandon TM848 drives?? I have a 4 or so of the slimline drives from some Tandy Model 12/16b units that don't seem to spin at all, and I've hooked them up to the same PSU that a TM848E successfully runs on, so I am guessing it's not a PSU issue. (Though, my understanding of 8" drives is extremely minimal, so...) If I could get just 2 of them working, that'd put a few 12/16b units back in operation.

Sun E250, NVRAM edit? (Serial Speeds, no console, etc)

by ethan＠757.org

Hello, I have an E250 Sun that belonged to a friend that passed away around 2008. It was colocated at a colocation office I had running in Virginia Beach. I pulled it out of storage, and would like to check if his public website is archived on it. Archive.org only has bits of it. Odds are low since it wasn't the main server, but worth a shot. I tried the usual Serial port A, but all I get is garbage. Tried all the common baud rates I could think of. If it's switched to diag mode, the diag stuff comes across in 9600bps. I tried the RSC port, it wants a password. Don't know it, didn't see anywhere online on how to reset it. I tried hooking up a console. Finally get the power brick in for the Samsung 770TFT LCD monitor I've held onto (it has 13w3.) At first it wasn't working. Tried both Type 5 and type 6 keyboards attached. No console. I found by removing the NVRAM, it will finally throw console. But no keyboard input. Stop-A, nothing. If I shove the NVRAM back in while it's running it immediatley goes black. Anyone know if the NVRAM strings are stored in plaintext in the NVRAM IC? If I were to dig out all the hardware that should be able to dump that chip is it something that is human readable / editable? I've done the coin cell hack on them before, but from memory the keyboard worked and it wasn't a big deal to do program in replacement MAC. But this is different, I need options removed. I'm thinking this thing has values in the NVRAM that are turning off the console and doing something funky to the serial baud rate. Or perhaps the baud rate in Solaris is set to something funky. - Ethan

Lear Siegler ADM-2?

by jacksonharrington22＠gmail.com

Hi everyone, I?m currently looking for a Lear Siegler ADM-2 terminal to purchase from someone for use in a future short film I?m creating. Afterwards I?d house it in my personal museum. If anyone has one or you know someone who owns one and could be interested in selling, let me know. I?d pay very well. I could also do a trade, I have quite a few rare terminals in my own collection. I?m familiar with old computers and know how to work around them, it could be in any condition. It would be in good hands. You can also Email me at jacksonharrington22 at gmail.com Thanks.

HP 16C Badge (logo)

by wh.sudbrink＠verizon.net

This is not exactly vintage computer, but it is very close. A friend just gave me an HP 16C calculator in excellent, working condition, EXCEPT the 16C badge (or logo if you prefer) is missing. I seem to recall that, some years ago, someone on this list knew of a source for replacements but I can't find it in the archive. So, I'll ask, does anyone know where to get a replacement 16C badge?

In search of 4B3A Microswitch Keyswitches (for a restoration, not a keyboard collector!)

by ian.finder＠gmail.com

I know what you guys are thinking- no, this isn't for a keyboard collection or some modern build or some other nonsense like that. I have a friend who is restoring a fairly interesting and historically significant vintage computer- a and subject to what appears to be a batch-related encapsulation failure on the proprietry hall effect sensors, but could have been some other trauma, around a little over half of them are bad. The correct SD-series replacement switch would be the 4B3A- *** These can allegedly be found on some of the Diablo printing terminals.** It is possible other switches ending in ***A could be made to work with a bit of labor and disassembly (swapping the fairly brittle sensors). I am not a keyboard expert but I have learned that you can remove a key on some of these microswitch keyboards and read the model fairly easily. Please let me know if you have a lead on a donor for these switches. They will be put to good use, and you can reply to me off list for more details. Thanks, - I

VCF Midwest Cancellation

by silent700＠gmail.com

We regret to announce... There will be no VCF Midwest this year. The conditions imposed upon us by the CoViD-19 pandemic and related government regulations, as well as a depressed expected turn-out figure, will make it impossible for us to host an event of the size and quality our dedicated fans have come to expect. Thus today we have terminated our 2020 contract with Waterford Banquets and the Clarion Inn hotel. We recommend cancelling your hotel and travel reservations, if you have made them, and we hope that you have not been too greatly inconvenienced by our change of plans. We also wish to express our thanks for the many responses we received to our survey sent back in May. Your feedback was informative, interesting, humorous and most of all, essential in helping us make the right decision about this year's show. The good news is that we have an excellent relationship with our host venue and have already locked in our contract for 2021. Although a long way off, plans will take shape early next year for that show, so please keep an eye out for further announcements of VCFMW 16 (or will it be 15b? We don't know yet!) Also, following the lead of other cancelled festivals, we are considering a Virtual VCFMW to be held on one or more of the dates allocated for this year's show (Sept 12 or 13, 2020). If we think we can pull off something half as entertaining as the real thing, maybe we'll do it. Watch your email for announcements sometime in August. Your humble(d) organizer - - jason If you would like to repost this message in your own forums, feel free to do so by using this link: https://us18.campaign-archive.com/?u=6d177060bd4511e27d05266a5&id=02ddfacc10

RK11-D "diskless" test ZRKJE0???

by bob＠jfcl.com

? I have an 11/04 with an RK11-D.? I have a couple of RK05s, but I wanted to test the controller before I start working on the drives.? The PDP11 Diagnostic Handbook says that ZRKJ?? "checks only the drive-independent logic of the RK11 controller. no drive is needed..."? I assumed that meant it was a diskless test, but now I'm not sure that's true.? Can anyone confirm or deny this? Does anyone have a listing of ZRKJE0? ? My RK11-D has the BC11 drive cable plugged into the backplane, but the free end of the cable is just lying on the floor.? No drive is connected.? The test fails with ??? RK11 LOGIC TEST I ??? MAINDEC-11-DZRKJ-E ??? REGISTER NOT CLEARED ??? ? PC?? REGADD??? RECVD ??? 002560? 177402? 100000 ?177402 is the RKER register and bit 15 is DRE - "Drive Error". According to the manual this bit is set when the AC power to the drive is lost, which given that I don't have a drive at all, doesn't sound unreasonable.? Continuing ZRKJ?? also gives ??? REGISTER NOT CLEARED ??? ? PC?? REGADD??? RECVD ??? 002560? 177404? 140200 ??? RKCS ERROR ??? ? PC??? WROTE?? READ ??? 002636? 000002? 140202 177404 is the RKCS register and the first two bits are ERROR and HARD ERROR.? These are both set by the DRE bit in RKER and aren't really a surprise. ? I'm starting to wonder if this diagnostic really works w/o a drive attached, or if these errors are expected. Thanks, Bob

Entrex 480 / Digital Computer Controls 116 in New Jersey.

by mattislind＠gmail.com

I just happen to see this auction: https://www.liveauctioneers.com/item/86804138_entrex-480-vintage-computer-e… Looks like three systems. One marked Entrex 480 the others look like the DG Nova clone DCC 116. On top there seems to be a Diablo printer of some sort. Some rust, indeed. In New Jersey. Then there another auction for several Diablo drives at the same location: https://www.liveauctioneers.com/item/86804145_sweda-750-computers-and-vinta… Also a stack of DG like cards and a core memory board, likely DG or DCC. Not in best condition but probably worth rescuing. Maybe someone in NJ area that want it? /Mattis

Ancient transistor ?computer board (Peter Van Peborgh)

by peter＠vanpeborgh.eu

OK, now here are some pics that should be available to everybody. I hope. https://photos.app.goo.gl/h64tye8ecmPHQfJD7 Smells of (early) 1960s transistorized. No helpful marking apart from * "GATE JJ01" on SIDE A. (components). * "C NT OL DATA" on side B (solder traces). Big transistors are Motorola "180376008". Also, any ideas what the "246 636 B" boxes are, they have four legs? A curse on TinyURL and praise to Camiel Vanderhoven. peter

MVME332XT documentation?

by cmhanson＠eschatologist.net

I?ve acquired a couple of MVME332XT (plus port panels and cabling) and was surprised to find that there?s very little documentation online, only a few references for setting up the board as part of specific systems. And a driver for it in OpenBSD 5.5?for their mvme88k platform only, because for some reason they don?t share drivers between all the VME platforms. Does anyone have scanned or printed documentation for the MVME332XT? How about document number MVME332XTFW, about the 332?s firmware? ? Chris Sent from my iPad

They were just the editors; most of the content was written by others. It contains a whole raft of individual documents, most of them RFCs, and some "NIC"s - similar documents available through the NIC, but generally only in hardcopy form (like the earliest RFCs). Many of the most important non-RFC ones are available here: http://www.chiappa.net/~jnc/tech/arpanet.html at the bottom of the page. I will create a page which lists the contents of the APH, since I gather it doesn't seem to be online. I'll email the list with the URL once I get it up. Any that are important, and not otherwise available online, I can scan; I've done one (NIC 29588) in the past. > If it's been superceded and the successor is available There were _successor_ documents, like the IPH, but they covered entirely different material.

Internet Archive and robots.txt

by a.carlini＠ntlworld.com

When I try http://www.openvms.digital.com/openvms/os/openvms-release-history.html in archive.org I get the usual: "Sorry. This URL has been excluded from the Wayback Machine." That's supposed to be because robots.txt prevents spidering so the Internet Archive takes down the pages (even if they were previously available, it seems). But digital.com is back and if you go far enough down https://digital.com/about/ you'll see that they know where the domain came from. So if whoever now controls digital.com could be persuaded to ask, would the Internet Archive allow those digital.com pages back out into the open again? (I'm asking here because I think there's at least one person on this list who might be able to provide a reasonably authoritative answer). I did happen to notice that dec.com is back too ...

Location of ARPANET Protocol Handbook or its successor, online

by will.senn＠gmail.com

Hi, If this is off-topic, my apologies, but I know some of y'all were there (Noel), so I'm hoping it's close enough to on-topic to garner a successful response. I'm looking for the ARPANET Protocol Handbook by Feinler, E. and Postel, J., published by SRI back in the day (revised edition 1978) in an online format (pdf preferably, but anything readable is fine. I came across the reference in RFC 790 - Assigned Numbers. If it's been superceded and the successor is available, that would probably work, too. Although, I prefer the earlier works for concision. Regards, Will -- GPG Fingerprint: 68F4 B3BD 1730 555A 4462 7D45 3EAA 5B6D A982 BAAF

UUCP on macOS / *BSD

by cctalk＠gtaylor.tnetconsulting.net

Does anyone have any experience with UUCP on macOS or *BSD systems that would be willing to help me figure something out? I'm working on adding a macOS X system to my micro UUCP network and running into some problems. - uuto / uucp copy files from my non-root / non-(_)uucp user to the UUCP spool. But the (demand based) ""call (pipe over SSH) is failing. - running "uucico -r1 -s <remote system name> -f" as the (_)uucp user (via sudo) works. - I'm using the pipe port type and running things over an SSH connection. - The (_)uucp user can ssh to the remote system as expected without any problems or being prompted for a password. (Service specific keys w/ forced command.) I noticed that the following files weren't set UID or GID like they are on Linux. But I don't know if that's a macOS and / or *BSD difference when compared to Linux. /usr/bin/uucp /usr/bin/uuname /usr/bin/uustat /usr/bin/uux /usr/sbin/uucico /usr/sbin/uuxqt Adding the set UID & GID bits allowed things to mostly work. Aside: Getting the contemporary macOS so that I could edit the (/usr/share/uucp/) sys & port files was a treat. I figured that it was worth inquiring if anyone had any more experience / tips / gotchas before I go bending ~> breaking things even more. Thank you. -- Grant. . . . unix || die -- Grant. . . . unix || die

More DECnet/E items

by tony.nicholson＠computer.org

Hi Paul, Thanks for posting some Y2K fixes and enhancements for DECnet/E under RSTS/E. I've also used the Bitsavers source files for RSTS/E V10.1 to fix a Y2K bug with handling RT-11 Y2k3 dates by the FIT program. Are you interested in including my patched FIT.TSK for RSTS/E along with your fixes. I could also provide my modified BASIC-Plus source code to FIT too (but releasing this too may have copyright limitations). Also I remember seeing a Y2K patch kit from Mentec for RSTS/E V10.1 on a TK50 tape. I don't have a copy of it - but I think it also had some additional Y2K fixes. You wouldn't also have some of these too? Thanks in advance. Tony -- Tony Nicholson <tony.nicholson at computer.org>

UUCP on macOS / *BSD

by cctalk＠gtaylor.tnetconsulting.net

On 6/28/20 6:48 PM, Grant Taylor wrote: > Does anyone have any experience with UUCP on macOS or *BSD systems that > would be willing to help me figure something out? I ended up getting this to work. I don't know if it was a macOSism or a *BSDism, but the root of the problem was crossing between users via setuid / setgid in relation to OpenSSH. Two different versions of macOS behaved differently. macOS Yosemite 10.10.5 runs the underlying ssh pipe command as the user account that initiates the uucp / uuto / uux. macOS Catalina 10.15.15 runs the underlying ssh pipe command as the _uucp user, NOT the account that initiates the uucp / uuto / uux. As such, on macOS Yosemite 10.10.5, I have to have the normal user's ssh public key in the authorized_keys file on the remote system. Conversely, on macOS Catalina 10.15.15, I have to have the _uucp user's ssh public key in the authorized_keys file on the remote system. I don't know why macOS Yosemite 10.10.5 and macOS Catalina 10.15.15 are behaving differently, but they are. These inconsistencies made identifying which client ssh config file -- nominally ~/.ssh/config -- was used cumbersome. For some unknown reason, I couldn't rely on "~/" or defaults to specify the _uucp user's key (Identity) file or the known_hosts file on macOS Catalina 10.15.15, despite the fact that it was running as the _uucp user. I ended up having to hard code the paths, as they were defaulting to the original user account that initiated the uucp / uuto / uux. I can only surmise that something is fundamentally different between Linux and macOS in how it does things when changing user accounts via setuid & setgid as I did not have any of these problems on multiple Linux machines. I can further surmise that something is different between macOS Yosemite 10.10.5 and macOS Catalina 10.15.15. I don't know if this is related to System Integrity Protection or something else. -- Grant. . . . unix || die -- Grant. . . . unix || die

HP 21mx computers For Sale

by steerex＠ccvn.com

Hey guys, I was a regular poster and reader on the list many years ago. During that time, I collected a few HP computers and Tape drives and a bunch of other "junk". Well the time has come for me to unload some of the equipment and I'd really like it to go to someone that has an appreciation for what is it. Currently I have 6 HP 21mx computers and about 30 I/O cards to move. I also have 4 7980 (or similar) auto-loading tape drives. They are top loading with HPIB interfaces. I also have a HP 9000 800/F20 computer that dual boots HPUX 10.20 or HPUX 11.0. from a SCSI array. It has ethernet, HPIB, and SCSI cards. It been a few years since I powered up this stuff. Everything has been stored indoors in a clean environment so I expect it to be fuctional. As far as I can tell everything is in EXCELLENT condition! This stuff is located in western North Carolina not far from Asheville. Because of the size, this would require local pickup. I do not have the means or inclination to ship. Notice I am not giving them away but will consider reasonable offers on any single item or multiple items. If interested, please contact me directly. Thanks, Steve Robertson steerex at ccvn.com

Bringing up MVME 197LE (88k)

by ryan＠hack.net

Anyone have experience with the Moto 88k VME boards? I have an MVME197LE that I?m trying to bring up but it?s staying in BRDFAIL, while SYSCON and RUN are green and pressing RESET appears to work. Nothing on console at all. (via a 712 transition module) Same behavior with the NVRAM removed. I do have the mezzanine card which has stayed affixed with an interesting inter-board connection. (Is this separate-able? Should it function without this DRAM?). I?ll dive deep into debugging this, but if anyone has some tips or experience they could share it would be appreciated! Thanks! -Ryan Brooks ryan at hack.net

IDE-SD adapter question

by w2hx＠w2hx.com

Hi all, Thanks for previous help on this project. I am working on an old 486 computer and I have replaced a 40 pin IDE hard drive with this SD adapter... https://www.amazon.com/gp/product/B07G29TZPS/ref=ppx_yo_dt_b_asin_title_o01… In general it seems to mostly be working. I can see a directory listing of several thousands files located on a 2GB SD card from yesteryear. The SD card was new when I installed it (has been in my possession for years). However, I do get errors "sector not found" and if I A)bort I get INT 24 error. I am trying to get windows 95 installed and this is certainly preventing that. In the BIOS settings I have the hard drive set as "USER" and these parameters: CY:[1024] HD:[16] ST:[63] LZ:[1024] WP:[0] These were the parameters in use while I was still using the actual hard drive. Question 1: Now that I am using an SD card instead of an IDE drive, what, if anything, should I be doing with these BIOS parameters? Question 2: The BIOS has an option to format the hard drive. Should I format the SD card using this facility? I did not explicitly put a filesystem on that SD card. I placed it in a windows 7 machine, it was recognized, and I began copying files to it. I then place the SD card into the 486 machine where I saw the sector not found errors. Any advice how to proceed? Thanks Eugene

FS: Video Toaster partial system

by jplist2008＠kiwigeek.com

A person on Reddit picked up what appears to be part of a Video Toaster and is interested in getting it to someone who can actually use it. I offered to pass on the message- The system is in a PC case, with two full-height 5.25" Seagate SCSI disks and a third-height 3.5" IBM SCSI disk, plus an optical drive and two 3.5" floppy disk drives. There's a standard-looking AT power supply and a (looks like) passive 16-bit ISA bus that has a single card in it which matches a NewTek TBCii "Time Base Correction" board. Pictures here: https://imgur.com/gallery/lqmRz6i They do want money, but not much, although shipping might be a bit steep for a case of this size and with the weight of the PSU and two full-height disks. I am not sure of their location, I got the impression (possibly wrongly) they were US based. eMail address is: shishkebarbarian at gmail.com I have no affiliation with the seller and all information is derived from the images taken, so do please contact them directly. - JP

A tool many of you may make find useful!

by dave.dunfield＠gmail.com

>Downloading http://dunfield.maknonsolutions.com/dos/sw/ddw2020.zip >gets flagged by Windows Defender on Windows 10 Pro (1909) >as "Worm:Win32/Spybot". A new tool now available on the site: Daves Distribution File Checker I have received reports that Windows Defenfer incorrectly lables some of my executables as naughty. I assure you this is not the case when published. They are freshly compiled from my own/known source code on a secure system. To help you know files are exactly as I uploaded then and not compromized in transit, I created this tool. It uses a proprietary/unpublished algorithm and multiple encrypted CRCs to validate that a file is exactly as I published it. The tool which makes the database will never be distributed in any way. You can check a complete .ZIP archive or individual files from it. The archive does not have to be present for DDFC to check individual files, but you do have to specify it so DDFC knows which file to reference in it's database. This program and it's database are self protecting, but can't insure they don't get replaced by something that looks the same without providing the protection. To help avoid this, I will reload this file every time I update my site.

Zenith MinisPort laptop memory issue?

by rickards＠gmail.com

Hi All, I'm restoring a Zenith MinisPort laptop, an 8088 based laptop with a monochrome screen and 2" floppy drive. I have a Twitter thread of the restoration so far with pics: https://twitter.com/paulrickards/status/1272280795529519105 I recapped the internal power supply board which seems to be working well now. The next issue appears to be memory. The unit won't store the BIOS settings properly, even with new lithium batteries or warm restart. In the BIOS menu, setting the clock with a "0" changes to "32". Same with the date, if you set the day or month, it adds 32 to it. The internal memory test reported a memory error at B800:0000 bit 5. This seems to coincide with the BIOS "0" turning into 32 on screen. When it eventually boots from the internal MS-DOS 3.3 ROM, it looks fine until the screen starts to scroll. The character case of all text on the screen changes from lower to upper case. Anyone know how to map a bit 5 error to a component on the motherboard? Would a memory map help here? Longshot: anyone have a service manual for the Zenith MinisPort ZL-1 (or ZL-2)? Thanks, Paul Rickards biosrhythm.com

On: raising the semantic level of a program

by sieler＠allegro.com

Hi, Not hardware ... but an antique software / programming concept. Some decades ago (circa late 1970s?), I *think* I came across a concept of "raising the semantic level" of a program by using defines/macros and newly written library functions. The concept was that a given language provided a particular level of semantics. By judicious/clever use of things like macros, one could "raise" the level of semantics, effectively appearing to add new features to the language (or, in this case, the instance of the language as used in the program). I *thought* I got that concept from Terry Wingrad's excellent "Breaking the Complexity Barrier again" (Nov, 1974, https://dl.acm.org/doi/10.1145/951761.951764 ) ...but, no. It's not in that paper. Does the concept ring a bell? Can anyone provide a pointer to where I might have seen it? It's formed the basis of my own personal programming philosophy for nearly 50 years, and I want to know where I found it, or if I might have thought of it myself. thanks! Stan

RSTS/E has just had its 50th Birthday...

by jnc＠mercury.lcs.mit.edu

> From: Peter Dick > As I expect you know, RSTS was 'born' on 11th June 1970 as shown when > you print DATE$(1%) ... > This means RSTS/E, the Greatest Operating System ever, has just turned > 50 years old. Err, I expect that that was RSTS-11 in June, 1970, not RSTS-E. Since RSTS-11 (which I learned to program on; happy memories :-) was a BASIC-PLUS only system, and ran on a PDP-11/20, I suspect it was a fairly different operating system (although no doubt it's BASIC-PLUS interpreter was ported to RSTS-E). I think RSTS/E needed the -11/45, introduced around June 1972; sources give 1973 for RSTS/E. Noel
