eBay VAX-11/780 has a few minutes left...

simh VAX 11/780 tech support

by jon＠jonworld.com

Folks, I'm trying to get BSD 4.2 running on a VAX 11/780/simh setup. This is working well under OpenBSD. I have the 4.2 BSD VM up and running. I'm having difficulty with networking. I'm using the pre-compiled simh package from OpenBSD which has networking support and running it as root to make sure it has access to the network interface. simh seems to be attaching to the network interface; I'm getting status messages about how Eth is attached, etc. simh is 3.9. No network devices to show up under the OS, though. Given that 4.2 BSD has TCP, is made for VAX, etc, the default kernel should automagically detect the network "card" presented by the emulator, right? For some reason it isn't. I also tried the other xu type=deluna (I think that's it, I don't remember from memory.) Here is my boot.ini set cpu 128m set rq0 ra81 att rq0 rq.dsk set rq1 dis set rq2 dis set rq3 dis set xu enabled set xu type=deuna att xu0 em0 set rp dis set lpt dis set rl dis set tq dis set tu dis set tti 7b set tto 7b load -o boot42 0 d r10 9 d r11 0 run 2 Is it an ordering/address space thing? Do I have to throw the "xu" stuff further down in the file? Thanks! -- -Jon Jonathan Katz, Indianapolis, IN.

Current verrsion of SimH for a PDP11 which runs under Windows 98SE in a DOS Box

by jhfinedp3k＠compsys.to

I never thought that I would be asking for this again, but after 10 years (my current version of SimH is V2.9-11 from 2002) I think it is reasonable to check out some new code on the current version of SimH. While I still run SimH from a Dos Box under Windows 98SE, I also run under Windows XP. I use SimH so rarely that I never bothered to generate a variant to run a PDP-11 under Windows 98SE for myself. But I have some new code which needs to be tested under as many different emulators and hardware as possible. The new code runs correctly under the newest E11 and that old 2002 SimH. I want to be sure that the code also runs correctly under the newest SimH and DEC hardware. So, can anyone please help with a link to a PDP-11 variant of SimH that runs in a Dos Box or just e-mail me a copy? While I am running these tests, does anyone use any other emulators than E11 or SimH? Charon used to be available, but does not seem to be around any more. Jerome Fine

----- Original Message ----- Date: Thu, 13 Dec 2012 11:12:04 -0500 From: David Riley <fraveydank at gmail.com> I'd be willing to bet that Pittsburgh is not a small city relative to most in Manitoba. It's actually not even that small relative to Philadelphia or Baltimore, neither of which I'd consider small. That said, Manitoba is an AWFULLY big province. You could probably find someone with similar interests, though they might be a fair distance away. ----- Reply: As a matter of fact Pittsburg's population is twice that of the entire province of Manitoba! It may indeed be a big province (almost the size of Texas), but its total population of around 1,250,000 scattered throughout that big province is half of Metropolitan Pittsburg's 2,500,000...

Fwd: Retrochallenge 2013 Winter Warmup - Registration Now Open

by mark＠wickensonline.co.uk

Entry now Open for Retrochallenge 2013WW! Entry is now open for the 2013 Winter Warmup Competition to be run between January 1st and January 31st. Please email /wgoodf at googlemail dot com/with your name (or handle) a brief synopsis of your project and a URL for your blog. About Retrochallenge In a nutshell, the RetroChallenge is a loosely disorganised gathering of RetroComputing enthusiasts who collectively do stuff with old computers for a month. The event is very much open to interpretation? individuals set there own challenges, which can range from programming to multimedia work; hardware restoration to exploring legacy networking? or just plain dicking around. It really doesn?t matter what you do, just so long as you do it. While the RetroChallenge has its competitive side, it?s not really a contest? it?s more like global thermonuclear war ? everyone can play, but nobody really wins. Come on? give it a go! Competition Rules 1. RetroChallenge commences 1st January 2013 and runs until 31st January 2013. 2. In order to qualify, computer systems must by approximately 10 years old (or older!) however exceptions will always be made for exotica! 3. Gaming consoles and PDAs qualify if they were made in the previous century. 4. Where appropriate, replica hardware and emulators may be used. 5. Entrants are responsible for adequately documenting their projects and submitting occasional updates during the contest. 6. Projects may encompass any aspect of retro-computing that tickles the fancy of the individual entrant. 7. Winners will be carefully selected and thoughtfully chosen prizes presented (hopefully before the next challenge commences). 8. Have fun! http://www.retrochallenge.net

It's realllly slow (about 25% slower than the 11/750) but physically small and only has 5 memory slots for 1MB boards. Using TU58 as the console boot medium made booting even slower, but if you copied all the files off of your tape (with EXCHANGE) and built a new tape (also with EXCHANGE), you could order the files properly and since the TU58 microprocessor appeared to cache the directory track(s), loading was then sequential and *substantially* faster. The 11/730 wasn't so bad if you used it like a single-user workstation. -ethan

FFS? HP/3000 (?) Parts

by jon＠jonworld.com

Folks, In going through my archives/basement I found three HP 12747H 64K Memory boards. I have no idea if they work or not or if anyone is interested in them. I received them around 12 years ago when a former customer was decommissioning an HP/3000 and they were giving out the internals as mementos to the staff. Shipping would be from 46219. -- -Jon Jonathan Katz, Indianapolis, IN.

Unobtainium obtained!

by ggs＠shiresoft.com

I just thought that I'd let folks know that I scored a bit (ok quite a bit) of unobtainium in the form of Unibus receivers and transceivers. It wasn't cheap but I just received 100 DS8640Ns (Unibus receivers) and 500 DS8641Ns (Unibus transceivers)! I would have gotten some Unibus drivers too if they were available. I think I'm now set (including the stock that I had previously) for the projects that I need them for (now I just need the time to actually work on those projects). Before anyone asks, these were obtained through a supplier on the secondary chip market. They only deal with commercial entities (one of the reasons I have one) and aren't interested in "small" quantities. It's hard to get them interested in an order under $1000 (and my total order for the above parts was well over that). TTFN - Guy

Nuclear Data ND-812 info...

by jim.mainock＠billjacobs.com

Josh, I just seen your post on the BR2412 and thought I might be able to shed some light on the ND812 Computer. I worked for Nuclear Data when they designed and started production of this computer. Nuclear Data prurchased DEC PDP8 and PDP11 computers to to process data from their nuclear instrumentation products and decided to build a system simular to the PDP but with an enhanced instruction set and floating page. The software developers created a point of sale demo and tried to sell it to McDonalds Corp. They laughed and said no thanks. The sales people then show the system to Jewel Foods and they decided to partner with Nuclear Data. Nuclear Data was loosing money and redesigned the system with the new spec 16 technology how ever the spec 16 was delayed for a year and Nuclear Data was forced into selling the point of sale division of the company to Bunker Ramo that is where the BR2412 model designation came from. I personaly trained most of the new technicians we hired on troubleshooting the BR2412. My last job at Bunker Ramo was running the test engineering department and then I went back to work another year after the sale at Nuclear Data. Nuclear Data was one of the best companies I have worked for. If I can aswer any questions you might have on either Nuclear Data or Bunker Ramo feel free to contact me via email. Thanks, Jim Mainock Jim.mainock at gmail.com

Old Unibus VAXen (was Re: eBay VAX-11/780 has a few, minutes left...)

by elson＠pico-systems.com

It's been more than 25 years, so my recollection may be hazy, but I think we had 208V 3-phase. I don't recall if it was delta or wye configured, but I tend to think it was the former. CPU from one phase, disk and tape drives from the other and our two big CDC line printers from the third. But as I said, it's been over 25 years since the electricians installed the stuff. We just went by what they recommended. Chuck Yes, our 780 was 208V 3Phase, and I'm PRETTY sure it was 5-wire, so it had a neutral and a ground pin. I think some of the outlets are still in the wall at work, so I'll check the twist-lock to see. I think the power supplies could run off 240 V as well, but possibly the whole machine was slightly different for that option. I know our big data center with IBM 370s was all 208 V also. The multiple H7800 (I think) power supplies each ran off a single phase bridged between two hots, but they were distributed around the phases. The LSI-11 and maybe a few other things ran off 120 V, and I think there was a scope/etc. 120 V outlet there, too. The big cooling blowers were each across two different phases. Some of the larger disk drives had 3-phase motors, and the high-end tape drives (TU-76, TU-77) had 3-phase power supplies and vacuum blower motors. I think the Vax 11/750 was single-phase 220 V, and the 730 was 120 V. Jon

Piecing together an HP9880

by ard＠p850ug1.demon.co.uk

I am not sure if this is on-topic since the machine involved was sold as a calculaotr. On the other hand, it programs in BASIC, it's getting on for 40 yuears old, and I am thinking of adding a hard disk. Classic computer? The HP9880 is the hard disk (14" platters) for the HP9830 'calculator'. I am slowly gathering the various bits of this system, I would love to get it all working again. As I understnad it, you need : An HP9830 calculator, HP9866 printer Mass Memory ROM module HP11273B 'cable' from the HP9830 to the controller HP11305 disk controller HP11302 cable from the controlelr to the drive HP7900A disk drive (one fixed, oen removeable plater) + PSU (or HP7901, which has only the removeable platter, but has an internal PSU) System tape cassette for the HP9830 Disk packs (of course). Now, The 9830 and 9866 I have, working. The HP11305 controller and both 'cables' (I put that in quotes becase thes cable assembleis have PSBs stuffed with ICs at at elast one end -- the 11273 has over 50 ICs in it) I also have, untested, but I know th PSU is good and the microcde ROMs look OPK (the disassebmyl of the mcirocode makes sense). Since everything else is standard TTL, analogue or RAMs ICs, I think that's reparaiable if necessary. I have the scheamtics and micorocde source for all that. The HP9800e emulator includes a dumo of the Mass Memory ROM, and thus I have it in an EPROM module. That emualtor also has an image of the ssytem and service tapes for the 9880, but as yet I haven'tt figured out the format of the image file or how to get them back onto physicl cassettes. I do have another tape drive mechansim (not HP) which sould be able to produce compatible tapes 'Just' a little matter of figuring out how ot interface it to soemthign and use it. At least I ahve the handbook for said drive, it includes timeing diagrams and schematics. Which leaves the drive and packs. This is the problem, I susepct I do havev a 7900A. Alas it was in a skip (dumpster) and had a 2100A thrown on top of it. The 2100A survived. THe 7900A is more sdubious. The front was samaged when it was gtaken out of the rack too. It's missing the terminator and the little card edge conenctor PCB, but those are easy to make I think. It's going ot need work. I also don't have the PSU for it. This seems ot be 120C AC (not isolated from the mains) for the blower and spindle motros), unregualted +/-24V and regulated +5V, +/-12V. Nothing difficult, but I can see myself speding time and moeny making something and then find the heads will no logner fly. I susepct replacement heads are not exactly common, I wonder if RK05 heads can me made ot fit? According to the HP nanual for the drive, there was a text/service unti for this drive, it conencted ot the side of the backplane. I cna't rememebr the model numebr (HP13219?). Hase anyone ever seen one, or have the manuals for it? And now for the pack. It's the same physicla size as the RK05 pack, but 24 (hard) sectors. Of coruse there's the fixed platter in the 7900A drive with it's own 24 sector hard dsetoy rign nad transducer. I belived the drive will spin up with any pack in it, so I could put a 'scratch' 12 sector RK05 in there to (a) see if the heads will fly and (b) see if I can use the fixed paltter (which will be 24 sector) drom the HP9830. If I get that far, I guess I then take an RK05 pack apart and attempt to put anotehr 12 notches i nthe sector ring. I beleive I then have to re-centre the platter on the hub which will be 'interesting' What if the heads crash? Maybe try to fit RK05 heads (I have some brand new spares here). Maybe try to interface an RK03 or RK05 to the HP contorller. The interface is differnet, but at least the data rate is the same. It woudl take a bit of logic to get it to work, but... If all else fails, make a solid-state repalcement for the drive? I gueess the questions at the momnet are : Anyone know the precise details of the tape image file format for 9800e? Anyone ever manage to fit RK05 heads into an HP7900? Anyone ever managed to cut the ectra sector notches? Anything knwon about the disk service unit for the HP7900? Does anyone have any comments/thoughts. Am I totally crazy for trying to do this? -tony

Seeking information on some Qbus disk/tape controllers: Dilog DQ37, Emulex QT131 and UC07

by ethan.dicks＠gmail.com

Hi, All, I was going through a box of "interesting" cards last night and I came across three cards that I'm looking forward to using: o Dialog DQ37 - an S-box-handle Qbus SCSI controller o Emulex QT131 - a Qbus Pertec tape controller? o Emulex UC07 - a Qbus SCSI controller I found the UC07 manual on Bitsavers, so I'm good there for setup and configuration, but I was curious if anyone knows about different firmware revisions I should be aware of or seek to put on the card (I've owned plenty of Emulex communications controllers, and done plenty of firmware swaps on those, and since they put firmware (ROM chip) upgrade instructions in the manual, it makes me practically expect to have to do something to it). I could not find more than a couple of comments about the QT131, but I'm reasonably certain whatever jumper settings are on there are a) the defaults, and b) just fine. If anyone here has any experience with the QT131 or even better, a manual, that would be appreciated. As for the Dilog DQ37, I can find nothing except 3rd-party resellers offering to sell me one if I click the "give me a quote" button. The ones I have (2) appear to have the single-ended SCSI portion of the board populated and have a large bare patch that, from the component values on the silkscreen, seems to me to be for High Voltage Differential. No biggie. I don't have any HVD drives anyway. I don't own any S-box hardware, so "just plug it in an see what it looks like" is not the preferred method - I'd like to know more before I go further. I'm especially wondering if this is a TMSCP-only controller or if it will do MSCP and/or TMSCP, and if there are any firmware variations I should know about. So... anyone here know about these cards or where to find docs (besides the UC07 docs on Bitsavers)? Thanks, -ethan

Paying work: Read a 9-track VAX tape in So. Cal.

by elson＠pico-systems.com

Not in CA at all, but I have a working CDC Keystone drive and an interface to a PC. I recently hacked up a program to read any 1600 (PE) or 6250 (GCR) tape to a binary file. There is a c program that will then read VMS Backup tapes, and I have it running here and have read in a couple of my old backups. I can also unpack some standard tape formats such as ANSI-D. I'd be willing to try this. But, I have had problems with old tapes that have been stored in bad conditions like attics or something. The oxide just peels off the tape like it was a Scotch tape or something, making a horrible sound. I'm in the St. Louis, MO area. Jon

Paying work: Read a 9-track VAX tape in So. Cal.

by cclist＠sydex.com

I have a customer in southern California who needs a 9-track tape from a VAX read and transcribed to something readable by modern equipment. I could do it, but it's not worth the hassle for a single tape for me. Anyone in the area want to give it a try? This is a paying job, not charity. If so, contact me with your details and I'll put you in touch. --Chuck

VCF Archive Fund Raiser Sale (Follow Up)

by sellam＠vintagetech.com

Folks, Forgive me, I do not follow the CC list so I didn't realize some comments and questions had arisen from my recent announcement of a fund raiser sale. First, as some bright fellows have already made clear, this is simply an offer to sell certain select items from what I have referred to as the "VCF Archives" unofficially since about the beginning (of the VCF). I am offering only duplicate machines for which I don't have an obvious need and that would be better off in someone else's hands in exchange for funds to secure the rest of the collection. There are only so many Altairs, Sol-20s and Cromemcos that a collection needs. As to the circumstances that have brought me to this point, that telling will have to wait for another day. It's a long story that would explain why I have been hibernating from the VCF for several years now (something I didn't initially intend to do but that became necessary over time). Most people wouldn't be prepared for it anyway, as it represents a departure from the person I was in this community for so long. Note, I did not say I am departing the community (not that I haven't had only a peripheral participation for the last several years) but that the person you all once knew has moved on. My interest in vintage computers remains, but it is an interest that has necessarily had to be put on the back burner while the universe imposes its will on me and I faithfully abide. This current operation is a winding down of Phase I of a life's work that will resume at the proper temporal markers. I will address some comments made in the original thread that are deserving of an answer. I invented the Vintage Computer Festival as a result of a discussion that I initiated on this list in the spring of 1997. Since then it has sprouted several sister events, including VCF East (presently the largest VCF event), VCF Midwest, VCF Southwest, VCF Southeast (just formed, produced by David Greelish of Historically Brewed fame), VCF Europa (Munich), and VCF UK. All of these events (except for the European events, which operate autonomously) can be accessed through the VCF portal (http://vintage.org) (historical note: remember when everyone was trying to create a "portal" to the internet in the early days? :) The main VCF held 10 regular events from 1997-2007 (skipping 2001, where the event was scheduled the week of 9/11). At the peak of the series we had about 600 attendees, and attendance for the last 3 shows was in excess of 500 visitors each. Ten is a good number. It is completion, and a new beginning. I had intended to take a hiatus from the VCF for a year. I was talked out of it on the condition that those who did the talking would be around the following year to contribute to the production of the event, as I no longer was willing to carry the full load of producing it (which is a failure of mine to properly delegate). No serious effort was mounted, as this was 2008, a financial collapse was imminent, and I had my hands full with other matters. I took my hiatus as intended. One year turned into 2, then 3, and now 5. The VCF is not done, but I believe I just may be with it, at least for now, other than a cursory hand in maintaining the website to support the sister events, and the main event, in the event someone finally comes forward to pick up and run with it. Quite frankly I became bored with the format. Don't get me wrong, the VCF is still a fun event no matter which one you attend, because it's all about old computers and old friends, and whenever those two combine then Good Times are had. But I wanted to do something fresh, something new, something absolutely mind-blowing. I was hoping to startup again in 2011, but it was not to be. Now, I'm looking to pass on the mantle to some sucker^H^H^H^H^H^Hambitious devotee who doesn't mind losing up to 3 months out of their life every year to continue producing the event. To clear up some misconceptions about the "Vintage Computer Festival" as an entity: - the VCF is not a corporate non-profit entity; - the VCF has never been a corporate non-profit entity; - I once considered attaining corporate "non profit" status for the VCF but instinctively decided against it, a decision that has proven its wisdom over time; - the VCF will likely never be a corporate non-profit entity; - if you consider the finances (revenue/expenses) of the VCF event in total, it probably did run as a "not for profit" all those years; it can be a profitable event, but it cetainly wasn't for the first 4 years; - while the "VCF Archives" is the unofficial name for my collection, it is in fact my personal collection, in the same way that the VCF is my event; it is all just my property that I offer to others for use through the VCF events and private arrangements; the fact is the collection has always been open to hobbyists at little or no charge throughout the years, and I have done well renting my services and pieces from the collection to various commercial interests over the past dozen years, including law firms and film production companies; - any improprieties suggested as a result of any of this are ignorant speculation. I believe that covers everything. Thanks to all those who have responded to my initial inquiry. Forgive me for not responding until today but I will be addressing each inquiry this morning. New inquiries are still welcome. I will also be posting specific items for sale to the list (I don't use eBay) and will eventually be relaunching the Vintage Computer Marketplace to conduct regular auctions of both my and others' vintage computer items. Lastly, I am not soliciting donations, but if someone feels compelled then I will not refuse it right now. I would consider any amount to be a blessing. Please contact me privately. I will follow this thread in case any further response is required. As always, I can be reached directly through private e-mail. Thanks! -- Sellam Ismail VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap...The truth is always simple.

Piecing together an HP9880 (Tony Duell)

by colineby＠isallthat.com

Spot on. The video in question is part of a bulk donation from an HP training centre. Its one of approximately 150 such titles in the TNMOC archive. They were distributed on U-matic and later VHS. Nearly all, even our UK-based set, are NTSC encoded. We have a little side project to dub them down to digital as a good 50% or more of this stock suffer from sticky tape syndrome. Even with periodic baking, the material is under threat of decay. I should note here, the TNMOC material was not donated with broadcast rights attached, but simply as a research resource. We don't have blanket coverage to YouTube the lot at present. All access will therefore have to treated as a normal research request. I'll happily relay all research requests back to the museum, though, and facilitate. Meanwhile, if any of you have the right contacts with HP to provide blanket YouTube publication rights please put them onto me and I'll try and get something sorted with our trustees. --Colin Steve Lafferty <steve at tronola.com> wrote: >At 05:53 PM 12/10/2012, you wrote: >>> I find that last statement farily hard ot beleive.

Ersatz-11 V6.1

by wilson＠dbit.com

After a long delay (it's hard to make big release-worthy improvements after 19 years of development), Ersatz-11 V6.1 is done. The free demo/hobby version is at: http://www.dbit.com/demo.html This release's additions are mostly about weird LSI-11-based microcomputers: - Terak 8510/a. This is a desktop machine with a standard LSI-11 CPU card and non-standard everything else. The highlight is the 320x240 graphics display. Runs RT-11/85 and UCSD p-System. Works in the DOS, Win32, OS/2, and stand-alone versions of E11, but not Linux (due to linker problems). Probably has plenty of rough edges since I've never even seen a Terak machine in real life. For one thing it only works with QX:-bootable disks (no QB: FDC emulation yet). - DEC PDT-11/130. LSI-11 chipset in a busless machine built into a modified VT100, with two TU58 tape units below the monitor. Runs RT11 SJ or FB, with more free memory than other MMU-less machines since it has a reduced I/O page (so 60 KB of main memory instead of 56 KB), and the guts of the TU58 driver are in ROM. DEC's PD.SYS driver is very small since it's just a shim. A reimplementation of the ROM code is supplied (since the original is copyrighted by DEC). - DEC PDT-11/150. As above but in a big desktop cube with two RX01s for storage. Again, comes with replacement ROM code to make PD.SYS work. The manual has an appendix that shows how to write "E11.INI" config files for all three of these micros. There's also a new built-in text editor; see the EDIT command in the manual. This was kind of an insane amount of work for just one new page of documentation! You already know how to use it (press PF2 for the keypad help screen if there isn't already a hardcopy scotch-taped to your monitor). It's mainly for editing your E11.INI w/o having to leave the emulation (or boot an OS in stand-alone E11), but it's an adequate basic text editor (it's a VT100ified 32-bit port of the DOS editor I've used for everything since 1983, including writing E11 itself). Another new feature that's just a rough cut is that the SET THROTTLE DELAY=d INTERVAL=i command can now take FILE=foo[.TIM] instead of DELAY=d. This way you can feed it a file (e.g. foo.tim) which contains 65536 little-endian 32-bit longwords, each of which is the average execution time of the corresponding PDP-11 opcode in nanoseconds. So now instead of adding a fixed d-microsecond delay every i instructions, E11 maintains a running total of execution time, and every i instructions it checks the actual current time and delays as needed to match. There's a lot of overhead in banging on the timer chip so often though, so for now the execution speed comes out slower than it should. The main fetch/dispatch loop is recompiled at runtime when the SET THROTTLE command is issued, so at least the overhead from this code vanishes when it's not enabled. Other new stuff: ASSIGN xxx /MAC:aa-bb-cc-dd-ee-ff works for *all* Ethernet devices (was just UDP:) so you can override the real port's default MAC address. And there's a new keyscript command that should have been there eons ago: "LASTSIMILARYEARBEFORE 2000" (you can use other years but why would you?) converts the current year captured by GETTIME to the last one before 2000 that had all the same days of the week, so you can kludge your way around non-Y2K-compliant PDP-11 OSes (this is for entering the current time/date with one keystroke at boot time if that's not obvious).

OT: how I outfitted my HP 16700A Logic Analyzer

by keithvz＠verizon.net

I wanted to buy an equipment cart to house the huge HP 16700A logic analyzer I bought, and I couldn't find one that would suit my needs. So I built it: http://www.techtravels.org/new_la_cart.jpg Specs were roughly * 2x2 solid wood Poplar frame construction * (3) 2'x2' shelves * Birch-Veneered 3/4" plywood * 2" casters * Monitor on left is floating above the top project area on flexible arm * anti-static mat * Surge protector for connecting equipment * sliding keyboard shelf * Ergonomically designed heights for keyboard/monitor It's far from perfect and weighs a ton, but it's pretty solid and I'm happy with it. Thought I'd share..... Thanks, Keith

More DEC keyboards

by kurt.m.nowak＠gmail.com

All - I have 3 more DEC keyboards available: 1) DEC LK401-AA with a hairline cracked bezel - probably easily glued 2) DEC LK401-AA with "gooified" feet 3) DEC LK201 No keys are missing and they seem mechanically sound, but they are a little dirty. I have no means of testing them, sorry. Asking $10 (plus shipping) for box/gas/driving hassle. Higher offers will jump to the front of the line. Take 1 or 2 or all three... I just want to get rid of them.

Need help with installing PDP-8 4k Disk Monitor

by michael.99.thompson＠gmail.com

For some reason the misbehaving TC01 controller on the PDP-8/I at the RICM decide work yesterday. Possibly due to the low temperature in the RICM warehouse. We took advantage of the situation and formatted and tested five DECtapes. Following the procedure in Appendix-A of the 4k Disk System Monitor System Disk System manual, we ran the DEC-D8-SBAF-PB 4k Disk System Monitor System Disk System Builder. We told it that the 8/I system does not have any disks or a high-speed paper tape reader. The System Builder wrote the Monitor, Loader, Command Decoder, Directory, and Storage Allocation Block Maps to the DECtape. We were able to enter the DECtape bootstrap program and boot the 4k monitor. The next installation step is to add programs to the DECtape. We continued with the procedure in Appendix-A.4. When the console displayed an ^ we entered a CTRL-P and then told the terminal emulator to send DEC-D8-PDAD-PB Disk System PIP-DF32 tape image. After sending about 1,500 characters the 8/I started echoing the characters from the tape image on the console and the command processor tried to use the input as commands. Somehow, after receiving 1,500 characters the 4k monitor switched from paper tape input mode to command mode. I am not sure if this configuration can be duplicated on one of the emulators. If someone could try the monitor installation and subsequent loading of programs from a real "Teletype" it would be interesting to see if it works. If it does work, then maybe we need to add the reader control circuitry to the 20mA/RS-232 converter that we are using to connect a PC to the PDP-8/I.

Help identifying ICs?

by snhirsch＠gmail.com

I have a sizeable number of Intersil 0.3" 14-pin DIP ICs (plastic package) with a part number "3-200-5" and a 1978 date code. Google turns up about 500 hits - all of them those obnoxious Chinese sites none of who have the chip or any data about them. How do folks work around all the "we find you chip fast, enter RFQ here" web sites? Steve --

cleaning up after the move.

by ba600＠ncf.ca

It's been a long while since my last post, and I should have cleaned up before moving rather than after. But I have a pile of monitors and external SCSI boxes that I'm not interest in keeping. Is there any interest or should these go to the recyclers. Apple monitors these came with the 2e all the way upto the LC's I think I only need to keep one or two so there are several spares Also older CGA and VGA monitors a few older terminals a pair of IBM PC 500 servers and 3 AS/400 9404s -- Collector of vintage computers http://www.ncf.ca/~ba600

VCF Archives Fund Raiser Sale

by sellam＠vintagetech.com

Dear CC Talkers and VCF Fans: The Vintage Computer Festival is currently securing funding for operations and storage of the VCF Archives for the next 6 months. As such, the VCF is conducting a limited sale of select items of the VCF Archives. As the VCF Archives pretty much contains everything, and due to current time restraints, the sale will be held as such: contact me (Sellam) with a wish list, and I'll indicate which of your requested items I could offer with a description and offer price. We can haggle out a deal from there. As my funding needs surpass my ability to deal with many small transactions, I am necessarily limiting the sales to items of a value of at least $250. This does not mean I will attempt to jack up the prices, but I would prefer to make single transactions that have a value of $250 or more. I apologize for the unorthodox nature of this sale but I am in an unorthodox situation and this is the surest way I know to raise the funds necessary to secure the archives. Please e-mail me with your wish lists directly. Thanks! -- Sellam Ismail VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap...The truth is always simple.

Hi! John Monahan and I have been working on an SVGA display compatible S-100 board and it is almost ready to go. While it is not SVGA register compatible it does allow for an economical SVGA compatible display for your S-100 system. http://s100computers.com/My%20System%20Pages/Lava-10%20Board/LAVA-10%20Board .htm http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=S-100%20LAVA Some additional discussion here on the vintage-computer.com forum http://www.vintage-computer.com/vcforum/showthread.php?30687 A viable PCB manufacturing order is at least 20 orders just to pay for the boards, tooling, shipping, etc. There are approximately 12 "firm" PCB requests and as soon as this project is viable I will make the manufacturing order. Thanks and have a happy holidays!

by slandon110＠gmail.com

What drew me to it was the .20 cent listing fees.. They only take a 3.5 percent cut of your final value. Pictures are free and you can list as much as you want. The listings last 3 months too which makes it even better. Feel free to chime in your thoughts on my pricing. Im listing a ton of vintage apple.

Opus ISA SparcCard

by paulyandy＠yahoo.com

Bernd, Greetings! I have a mysterious ISA card and after researching, I found an old post from 2007 which contained a conversation you were having regarding an Opus ISA SparcCard.? I'm curious if this is what I currently have. Do you happen to know of any online information about getting this working?? I was going to recycle it but it seems a shame if it is a bit of history and of unique functionality. Any help is most appreciated and thank you! Paul Anderson

Apple 1 and Altair set new records at auction

by lsprung＠optonline.net

Greetings everyone, I just wanted to bring the following 2 items to the lists attention. I'm surprised I've seen no discussion about the record setting prices from the recent Auction Team Breker sale last week where an Apple I sold for about $640,000 and an Altair 8800 reached $16,000. WOW! Does anyone have any insights to these? Do you think these prices were due to auction excitement or new global interest in the value of collectible computers? http://acn.liveauctioneers.com/index.php/auctions/auction-results/8714-apple -1-computer-sells-for-640000-at-auction-team-breker

SIMH images to Zip Disks

by fraveydank＠gmail.com

I have a bootable 100MB RSX-11M image in SIMH that I'd like to blast onto a Zip disk and boot through my CQD-220. I'm running a build on SIMH that's essentially identical to my machine, so it should be straightforward, but when I try to boot my disk, I get a "not bootable" response from the ROM (the activity light on the Zip drive does flash momentarily, so I know something is going on, but it doesn't look like it's taking enough time to actually seek anything (and when I boot through the bootstrap provided by the CQD-220 ROM, I get a HALT at 000002, which tells me it's probably getting all zeroes). I know at least some of you boot your -11s off of Zip disks, probably with similar cards. What am I missing? As far as I can tell, the SIMH disk image format is a headerless binary blob, but it doesn't look like I'm getting to the point where that even matters yet. - Dave

by jgessling＠yahoo.com

I wonder if that was originally from Tri-Valley Growers.? a very large agricultural Co-op based in Modesto (nearby) that went bankrupt in 1999.? They were heavy VAX and later alpha users and would show up fairly regularly at BAYVAX meetings back in the day.? Not sure about the graphics thing though, can't remember them talking about that, but it's been a while.? Just for fun I googled for "tri valley growers vax" and was surprised to see how many people out there have that on their resumes.? Pretty fertile ground for computer people as well as fruit.

P112 kit for latecomers

by dgriffi＠cs.csubak.edu

I'm now ready to take orders for P112 kits from people who didn't get onboard the Kickstarter project. For a complete kit (board and all parts that solder or plug into it), the cost is $200 to addresses inside the US -- $215 outside the US. If you want one (or more) please email me with your Paypal address so I can make up a proper invoice. Alternatively, I will accept check and money orders. If you want Terry Gulczynski to build and test the kit for you let me know and I'll get that set up. If you're outside the US and want this service, you can pay the inside-the-US price. I'll ship the kit to Terry. He'll charge you for his services and ship you your board. If you want to order a GIDE board at the same time, he can do that too for you. He'll also sell you the GIDE board by itself if you want to build it all yourself. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

I got in touch with Hector Parr, and he directed me to a memoir he's written, and I now have a story: One Alan Wilkinson wrote the book 'Computer Models' (a copy is now on its way to me) which is most likely inspired by Brian Crank's article series. Alan was teaching at Spennymoor Grammar School, and Hector was teaching at the nearby Darlington Grammar School. Hector read Alan's book and proceeded to get the Maths department and pupils to finance and build a machine called DENICE, designed from scratch but with inspiration >from the book. Alan moved on to Teesside Polytechnic where he looked after an IBM 1620, which was made available to schoolchildren. Hector later taught at Barnard Castle School, where he was photographed in 1978 with a different computer: http://ww2.durham.gov.uk/dre/pgDre.aspx?ID=DRE10345&PIC=Y His memoir can be bought at http://www.lulu.com/shop/hector-c-parr/music-maths-and-machines/paperback/p… - there's a copy of this too on its way to me. I now discover that Alan's book has been referenced at http://en.wikipedia.org/wiki/Transistor_computer#cite_note-15 since Nov 2010. (As for the reported cost of ?50 in the late 60's, I'm told a weekly shop for a couple would be ?2 and a pint of rough cider would be 1/9d (that is, 21 old pence, which were 240 to the pound.) According to http://safalra.com/other/historical-uk-inflation-price-conversion/, the project would cost ?750 today, although those anecdotal prices suggest rather more.) I wrote up some notes on the WW machine here: http://forum.6502.org/viewtopic.php?f=3&t=2333 Cheers Ed

HP 2113B psu question

by hp-fix＠xs4all.nl

One of my HP 2113B CPU's doesn't boot the right way, after switching it on all lights are on except the over flow light which stays out. I know it should be an memory error, but removing all the memory boards and starting with a known good memory controller and memory board gives the same result. Because the PSU has the power fail option and I removed the batteries and placed the plug at the battery in connector, I now suspect the PSU. The voltages checked out ok, except the 5M and 12M voltages come up a few seconds (5 to 10 seconds) later than the rest of the voltages. I'm afraid the time interval is too long but I'm not sure. Is there anyone who knows what the interval should be ? Or has any clou why it's not working ? -Rik

The System Console from the DEC PDP-10 KA-10 System #105 at BOCES-LIRICS was recently donated to the RICM. We are considering mounting a System-on-a-Chip to the back of the console and making it a "live" PDP-10. For more information on the console see: https://sites.google.com/a/ricomputermuseum.org/home/Home/interesting_compu… -- Michael Thompson

Remember the Model 1? I'm just letting the list members know I put a YouTube video up covering this classic This is the last notice I'll post on classicmmp.org regarding these videos. I intend to gradually cover all the machines I've got and I don't want to be accused of spam by using the list to notify people, even if some may be interested. Just subscribe to my YouTube channel if you want to be alerted to subsequent videos. Cheers Terry (Tez)

FPUIB: Esoteric crap (11/28/12)

Somebody clueless may have > looked at the DE9 and automatically labelled it as "RS232" (as a misuse, > meaning serial) Err, not necessarily. I'm rather thinking that the corresponding LCD projector ("beamer") might have included or at least supported a "presenter", i.e. a wireless, handheld mini-trackball or hat-switch type pointing device, whose signals are relayed to the host system via the respective pointing device interface. As only one of these interfaces is needed at a given time (ADB when connected to a Mac, either RS232 or PS/2 for a legacy PC, or USB for a modern one), it kind of makes sense to bring these out in a single connector (in this case, the DE15) and include the different adapter cables for connecting it to the host system. I got a similar set of cables some years ago, these had a not-quite-MiniDIN connector at the projector end and either DE9, MiniDIN-6 or USB on the other. They were factory labelled as belonging to an ASK C105. If so, very usefor for somebody having the corresponding projector, not so much for anyone else. Hope this helps - so long, Arno Kletzander

N8VEM home brew computing article

by LYNCHAJ＠YAHOO.COM

Hi One of the N8VEM builders wrote a draft magazine article that provides a great overview of the N8VEM home brew computing project. It is so good I thought other hobbyists would like to read it and better understand what we are doing. http://n8vem-sbc.pbworks.com/w/file/61597682/N8VEM%20article.doc Most of these PCBs I have physically on the shelf waiting to go to builders. Others will be reordered and builders always have the option of getting their own based on the information on the website. http://n8vem-sbc.pbworks.com/w/page/35044530/PCB%20Inventory Please send me an email if interested. Thanks and have a nice day! Andrew Lynch

Microvax II won't boot, hardware error?

by saquinn624＠aol.com

Make sure all your connections are firm and good, especially the PMI connection over the ribbon cable. I'd probably even take the ribbon cable off and re-crimp it in a vise to make sure the connections are firm.

In countries where BS1363 sockets are used, IEC power cords with BS1363 plugs on them just accumulate without anyone having to do anything. We use them here in Ireland and I've got a big box of those leads. (Anybody want some?) In other countries, they are not much use unless someone decides to fit out their workshop with BS1363 sockets.

Commodore PET 2001 Chiclet Keyboard Repair

by arkaxow＠gmail.com

I am working on getting a Commodore PET 2001 Chiclet keyboard working again. Some of the keys were not working. So I disassembled it and cleaned it. But some of the keys still didn?t work properly. I noticed that some of the keys had something metallic on the bottom of them and others didn?t. It appeared to be random. I talked to some friends and they seemed to think that that the rubber in the keys is a sorta conductive silicon. My suspicion is that this silicon becomes less conductive over time or is not reliable to being with. It seems that the previous owner had fixed some keys by adding some metal to the bottom of the keys. I think it is ordinary aluminum, but I am not sure. When I replaced one of the keys with the thin metal on the bottom to previously not working key, then it worked. My plan is to put this metal on the bottom of all the keys so that they will all work and be reliable. If anyone knows what kind of metal it is and where I can buy it, then I would appreciate it ! Thanks, Jeff Brace

Fw: 68360 help

by lynchaj＠yahoo.com

Hi Received a request for help on a MC68360 prototype board. This is an intermediate step to the planned MC68040 SBC. If anyone has expertise with the MC68360 and can help please contact me at LYNCHAJ at YAHOO.COM or on the N8VEM mailing list. Thanks! Andrew Lynch From: To: n8vem at googlegroups.com Sent: Sunday, November 25, 2012 7:58 PM Subject: [N8VEM: 15020] 68360 help Hi I have been working of the MC68360 prototype that would be the precursor to the 68040 build. ?I am stymied and would like any ideas on how to proceed. ?Attached are the schematics. ?What I observe on power up is that RESTH* is always low - it is pulled up with a 10K resistor. ? I have tried all kinds of things to figure out why this is so but can not seem to crack this. ?I feel if I can get past this always low condition I might be able to make progress would be greatly appreciated. ?I also have a couple of bare boards if anyone is interested in taking a stab at this. Thanks in advance? Dave--

TU58 tape formatter (was Re: rebuilding DC100A cartridges?)

by shadoooo＠gmail.com

Hello. Do you still have an image of the ROM data? I would study it a little, as producing a formatter (also using TU58 mechanics but different electronic) would be very interesting... Andrea > I've disassembled the firmware its not there. It's not that hard to do > the reason I say modded is the 8085 > has only has 256bytes of ram and 2k of rom on the board.

In the end you need the TU58 board for the drive interface > and motor control.
