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 hope Dave is OK. He lost his house in the big Colorado fires years ago and I haven't talked to him in years. I wonder if Johnny has heard anything from him.

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
