Hi all, I've posted looking for help with a TeleVideo TPC-1, and I've heard a lot of crickets - apparently this isn't a commonly held machine. :-) But I've made progress with it, which I want to share. When I first got it, the display would light up and ask me to insert a floppy. Doing so would promptly douse the display. I figured, 'power supply', and recapped the entire thing - after the venture of figuring out how to open the case! I found a post in netnews that strongly suggested TeleVideo had suppressed information about opening the case to protect their service centers' business.... It's an odd combination of 'push there, pull there and be bold', but I got it open. Recapping was a success, and the machine attempts to boot from disk 0 - and tries, and tries, and.... I figured that drive 0, being the most used, might have issues, but wasn't looking forward to pulling out the drive cage and swapping them as a test. But then I noticed that drive 1's circuit board was visible, and I rejumpered it to be drive 0 - and success, the machine booted into CP/M! Sure, I could just leave it as a single-drive machine, or swap the two and pray - but this is a restoration. I've ordered an exact, tested/guaranteed working replacement from ePay, and I'm going to have everything working to spec before I snap this thing back together. Yes, I'm having fun. :-) -- Ian S.

Gaming on old systems (was Re: Twiggys [was: Re: ka... ching!])

On Sun, Oct 9, 2016 at 4:58 AM, Peter Corlett <abuse at cabal.org.uk> wrote: > Find better games :) > > The theme of this list means that I should recommend some retro games and > gaming systems... I am actively seeking lists of favorite games on all platforms prior to 1995. Specifically, things that require Windows and a Pentium and newer are out of bounds. I'm attempting to breathe some excitement into a retro-gaming meetup I hold a few times a year at our hackerspace. I'm already bringing the hardware - to date, Commodore PET, Commodore 64, Apple II, Atari 2600, PDP-8 (emulated for now), and curses-based UNIX games, and would like to add more platforms. I'm especially interested in any favorites that run on dumb terminals (I have numerous ones to bring in, and have a VT220 already in the collection). Yes, I know a bunch of games that run on those platforms. I'm looking for other people's favorites because that is what will stimulate interest in the meetups. I already bring my own favorites, but learning what other people remember fondly - tapping into their nostalgia - will be a big help. In bounds are any machines from the 70s and 80s that a) are common enough to lay hands on or b) have a reasonable emulator on modern platforms. I will probably add DOS games to the list, but that's not the focus at first - 8-bit microcomputers and minicomputers are at the top of the list. Emulation via simh is acceptable but I'll try to dig up the original hardware where possible. If you've played anything in the past 3 years, I'd especially like to hear about it since that speaks to enjoyment and replayability. If you like it, someone here will probably like it too. Thanks for any and all suggestions! -ethan

Where are the cctech archives before November 2014 ?

by w.f.j.mueller＠retro11.de

Hi, I detected that links I had to previous postings where invalid. Looking at http://www.classiccmp.org/pipermail/cctech/ I see that the archives before November 2014 are lost. When I look into the WayBackMachine I see https://web.archive.org/web/20141025062159/http://www.classiccmp.org/piperm… https://web.archive.org/web/20150103042513/http://www.classiccmp.org/piperm… that between October 25th. 2014 and January 3rd, 2015 some incident happened which wiped out the archives before November 2014. How comes that the 'classical computing' lost it's memory ?? With best regards, Walter P.S.: It's a bit astonishing to me that a list like cctech, which is in some ways about history, has lost it's own history, and even doesn't seem to care about it.

Gould 32/77 (was: NWA auctions)

> From: Brad H > the 11/45 is from around the early 70s right? First released in '72, if memory serves. It was in production for a _long_ time, though - no later model really replaced it (if you wanted a mid-sized machine with a lot of crunch), unlike many of the other -11's (e.g. /05, /40, etc). Noel

Any Kryoflux, Discferret, Catweasel, or other floppy flux images wanted

by spacewar＠gmail.com

Would anyone care to donate floppy disk flux-transition images for use in development of utility software and for regression-testing the same? It would be much appreciated. Images from "normal" floppy formats (IBM FM and MFM, e.g., TRS-80, IBM PC, or almost anything using 177x/179x/279x or 765/8272 family controllers) and obscure formats (DEC RX02, Victor 9000) would be welcome. I'd especially like to get IBM 23FD "Minnow" disk images, but I'm not holding my breath for that. If you send me any images, a brief description of what they might contain and/or what system they're from would be helpful. I don't need to be able to do anything with the content; I just want to verify that I can extract the content from flux images into sector images. If you send me any images that you don't want made public, let me know. Thanks! Eric

IBM 6715 / actionwriter "daizy" typewriter "RS232" port ??

by gerardcjat＠free.fr

I know it is a long shoot ! The IBM 6715 / Actionwriter was one of the last daizy wheel typewriter made by IBM Germany. ( said to be made to last at least half century, German design ;-) ) It has "kind" of a RS232 port on the back, I was unable to find any information on this port which was intended to support two "extremely rare" !!! IBM options one beeing a REAL RS232 port, the other some kind of display of the two last line typed. I wonder if someone has even connected this typewriter to a computer. It would be fun to use it like a "modern" TTY but I think the problem is probably that this typewriter expect a "lot of" (??) proprietary commands to set type spacing, margins, baud rate etc .... Any advice ?? Any help ??

Highway interface [warning contains an ebay ref], but is an old VMS network interface

by jwsmail＠jwsss.com

I found an interface I've never seen, a Fisher Rosemont Highway interface. I don't know much in the history of Dec / VMS, but am guessing this is for Vax system only. HIGHWAY-INTERFACE-49A8569X052-62-FISHER-ROSEMOUNT-DC6450X1-HA5-40B1745-W-CABKIT-/ http://www.ebay.com/itm/371645465846 I found this flyer sheet about it with the info on the interface. I'm guessing if you don't have one of the central boxes, you have some expensive gold scrap in these boards. http://emersonprocess.com/systems/support/documentation/provox/docvue/Produ… The fact this reference is where it is suggests there must be embedded systems using it to justify the price though. Also the other manual referred to indicates that there is something that runs on NT, as well as a mention of AIX. http://emersonprocess.com/systems/support/documentation/provox/docvue/CHIP/… thanks Jim

PDP-11/23 system for sale in Portland Oregon

by scott.l.baker＠gmail.com

Update: After removing all the boards, checking jumper settings, etc. and reinstalling everything again. I am please to announce some progress. The PDP-11/23 now boots up to the diagnostic monitor. Thanks very much to people who replied with technical help and particularly to Glen Slick who helped with board identification and configuration and help me fix the QBUS slot assignments. The original slot assignments were wrong and the bus termination was not at the end of the QBUS. The current slot assignments are: Row 1: AB - M8186, CD - 256KB memory Row 2: AB - DSD disk interface, CD - grant continuity Row 3: AB - M8028 DLV11-F async interface / console port Row 4: <empty> Row 5: <empty> Row 6: <empty> Row 7: AB - M8016 KPV11 power fail / line clock Row 8: <empty> Row 9: ABCD - M8012 BDV11 diag ROM / QBUS termination I have added a few pictures here: http://sierracircuitdesign.ddns.net/temp/pdp11/ Next Steps 1) Find the manual for the diagnostic monitor to figure out how to run some test. 2) Locate some 8" floppies with RT-11 loaded and connect the floppy drive

Video clip from ABC Nightline 1981 with Steve Jobs

by jwsmail＠jwsss.com

If you read further, I decided to post because of the number of machines I've either worked on or owned which were in this. I think for instance the terminals @ about 1:29 are Datamedia. I had several of the beasts. "Academic researchers... is the narration" https://youtu.be/3H-Y-D3-j-M Laughed at some of the discussions in the last half, but worth watching. Has about as much of Job's in it as one can stomach. And is probably before the cult of the Fruit company thing was taking hold. Scenes showing the Apple2 or ][ as some will want, and the Apple3 are shown from the factory. Also appears that Apple was operating out of a hive of buildings, not a central one at the time. Five years into Apple's operation. Thanks jim

Micro Fiche Library.

by rodsmallwood52＠btinternet.com

Hi All I have just had a huge DEC Miro Fiche library given to me. It has the portable (weighs a ton) reader with it. On trying it out. I found the results were awful. A good clean of the light path and removal of some disintegrating foam improved things no end. That left two issues: 1. The reader was for x 42 but the fiches are x52. 2. The plastic fiche holder consisting of two sheets of stiff and clear plastic connected together at one end is scratched to hell. I'd like to work to-wards scanning all of the library into a system. Anybody know anything about fiche scanners. Rod -- PDP-8/e PDP-8/f PDP-8/m PDP-8/i Front Panels ex Stock - Order Now

Mark-8 opinion question

by vintagecomputer＠bettercomputing.net

I asked this on vcfed and I don't know how much overlap there is here so I apologize if this is hitting all the same people over again. As some are aware I recently won an auction for 9 original Mark-8 boards (it has 4 1k RAM boards). To say I was elated would be an understatement - I certainly have some unusual stuff in my collection but this is something truly rare. And these are rare both in their own right and for what they are - unused. Pretty much spotless. I feel kind of in a bind about it now though. As an amateur historian, my first impulse is to stick em in a frame and hang em. Not even lay a finger on them. But I've a stubborn practical side. Like that guy that has an original AC Shelby Cobra and actually drives the thing. He was asked why he'd actually drive such a rare and valuable vehicle and he said 'What's the point of a car you don't drive?'. But then he can say that - that Shelby doesn't have zero miles on it. Realistically, I'm never likely to own a complete, vintage Mark-8. There are simply too few of them and I couldn't afford one even if one popped up (I could afford the computer, just not the divorce afterwards :)). So here I am with one path to having one that would be, by virtue of the boards, way more legit than a clone, but still have that 'built in 2016' asterisk beside its name for serious collectors. Anyway, I'm just soliciting opinions from those I haven't already heard from. This is just for the purpose of discussion, because I'm sure this isn't the first and won't be the last time somebody buying vintage gear runs into a situation like this. Whatever I end up doing, it will not happen for years anyway. I'm not at a skill level yet to pull it off, and I'd still like to build that clone first and see what I achieve before touching priceless originals.

If it were me, I would not build on the originals. I would engage someone to repop the boards, their labour cost would be recouped with the sale of a few sets. What I would do is make sure the repops are easily identifiable as such so that they are not in future passed off as orignals at the same time as preserving your investment in the real thing. I recall seeing photos of a WWI biplane fighter being restored by the Smithsonian, and on the new pieces of wood they used to replace damaged or missing fillets, longerons and other parts of the airframe they had clearly stamped 'REPRODUCTION' so that future conservators would know > what was original and what was not. > Steve. Thanks Steve. No honestly.. I just like to talk about stuff like this. ?My mind is nowhere near made up. Regarding repopping.. I thought this had already been done by Obtronix or someone? I saw repop boards on ebay that I think the seller was trying to pass off as original. ?I'm wondering now how they made theirs and if in repopping mine I'd just be reinventing the wheel, or if someone could make them look that much more like the original.

I have it on my iPad, Android phone, Mac Desktop and a whole slew of Unix boxes (SGI/Sun/IBM/DEC) and even (ughhh!) a PC/Linux laptop... It's usually the first thing that gets installed/compiled on a new machine/platform. The only experience that will top the above, is feeding some quarters in a "Fun House" or "Black Knight" pinball machine...

Getting out of the hobby

by cramcram＠gmail.com

Sigh. For a second there I thought you were going to be getting rid of an 11/45. That would be my dream machine as I used one at Ohio State in the very early days (mid 70's) of computer graphics. I designed one frame buffer and part of another to run on that machine.

SCSI Tape Emulator

by seefriek＠gmail.com

I thought this sort of thing was what the various target-mode SCSI frameworks were designed for? I seem to remember at least one of them had emulated tape drives backed by files. KJ

Front Panels - Update.

by rodsmallwood52＠btinternet.com

Hi Firstly I am pleased to be able to say I have five different PDP-8 front panels all in stock. Secondly a big thank you to Jack Rubin for mentioning my panels in his presentation at the Chicago show. I have the artwork for the PDP-8/L done and I'll get a run done as soon as I get enough interested parties. Thanks to Vince I have been able to make a working PDP-8/i lights board. As we all know the 8/i is made up of a wire wrap back plane and loads of flip chip modules. I am only mad not totally insane. So reproducing that lot is not possible. So its the Raspberry Pi and simH route for me. First job is to go and have another look at what Oscar did/is doing. I know he muxed the lamps on his board. He usually open sources everything. In keeping with my plug compatible philosophy I'll go as far as paddle cards and DEC style edge connectors on my PiBoard The switches are the butterfly rocker type. I should be able to pick up an odd one as a sample. I know Oscar is looking at this whole question so I'll get an update >from him.

ISO Figure from ENIAC Technical Manual

by blstuart＠bellsouth.net

I know this is a very long shot, but I'm looking for Figure 6-13 >from the Part I Technical Manual on the ENIAC by Adele Goldstine. In the table of tables at the front of the manual, this table is one of three listed as "in an envelope attached to the back cover." Neither the scan on archive.org, nor the printed manual from Periscope Film, appear to include these tables. Does anyone by any chance know where a scan of any of those three tables (6-13, 7-4, and 8-13) might exist? Thanks in advance, BLS

VCF Midwest 11 Videos!

by silent700＠gmail.com

I am pleased to announce that the full lot of speaker videos from this year's Vintage Computer Festival Midwest have been posted to our YouTube channel. There is a play list of this year's videos here: https://www.youtube.com/playlist?list=PLE-Iywr9LQESedwj_46tFIaPoyrUf-mHs In addition to the fine lineup of speakers, there is a 7.5 minute "highlight reel" showing many of the varied demos and displays, along with some nice stop-motion footage of the crowd at various times of the day. The direct link for that is here: https://www.youtube.com/watch?v=adQIMM7cVg0 Although he is not on this list, I want to thank our full-time "A/V nerd," Jim Leonard (AKA Trixter http://trixter.oldskool.org), who handled all aspects of production, from manning the camera and mixer during the talks and clipping the lav mic on the speakers to his expert editing and production of all the footage. The highlight reel was his idea, too :) We're really proud of our interesting, diverse set of presentations this year, as well as having kicked the production quality of our videos up quite a few notches. We hope you find something of interest among them. -j

Chip info reqd: MR9736-002 CRT controller?

by witchy＠binarydinosaurs.co.uk

Hi folks, The restoration of the STC Executel 3910 I mentioned the other day continues with picture help from another collector who bought one at the same time I did. I've got it powering up and the tiny monitor is trying to display something but the horizontal hold has gone so I'm suspecting dry joints given the state of the back of the monitor board and the microcassette drive next to it when I opened it up for the first time. It's been cleaned and the leaky battery removed since then, fortunately there's no trace damage from the alkali. The display board is powered by the chip in the subject line and neither myself or google has heard of it. It's a 40 pin DIP that doesn't seem to be pin compatible with any CRTC I'm aware of. Anyone? -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?

I tried this with my > Digital Group system with 5 different tapes marked 'assembler' but never > got them to load.? Not sure if I understand the concept. The assembler is a program that transforms (somewhat) human-readable text into machine code.? There a few ways to go about structuring this workflow.? So far I've been using a cross-assembler that runs on a different system - for example, the original UNIX was cross-assembled on a GE-635 mainframe for its PDP-7 target.? There are native assemblers as well.? These often assumed some sort of secondary store, whether punched tape, magtape or disk, that might hold intermediate stages of assembly and certainly the final product.? A common workflow was: - load native assembler program from <media> - start native assembler program - tell native assembler program where to find the source (which media) - native assembler reads in source, transforms it to object (machine code), sends the results to <media> - programmer loads object from <media> and runs it If you're loading an assembler program from tape, you probably need to give the monitor a 'go' instruction once it's completed (that's how MIKBUG works, anyway).? The assembler may prompt for the input source or may just assume that once you say 'go' a tape is loaded and ready to be read. How do you create the source?? If you're doing it natively, you need an editor that runs on the platform and can send the resulting text to <media>.? Or again, you can write your assembly source on another platform and create (or emulate) appropriate <media>. I hope that helps.? Cheers -- Ian -- Ian S.

So the Cliff Notes version of this is I need to find a copy of SWTPC's assembler? ?(Pretty sure I've seen it referenced somewhere)

SCSI Tape Emulator

by dave.g4ugm＠gmail.com

Folks, I am "playing" with a small VAX and want to install software onto it, some of which are in SIMH ".tap" format files. I was thinking it would be nice to have a SCSI Tape emulator that worked a bit like the USB floppy emulators that are about. So it would plug into the SCSI bus and allow ".TAP" (and other tape formats) stored on some kind of flash memory, say USB or SD card perhaps, to be read by real hardware. Does this sound usefull to any one? Any other thoughts on how this could be achieved? Dave Wade G4UGM & EA7KAE

Data on a Platter!

by silent700＠gmail.com

Here's a scan - and special bonus audio tracks - of a brochure and 7" record I found on ebay recently: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/EG%26G "Data on a Platter" from a company called EG&G (anyone heard of them?) describes their vinyl (as in analog audio record) data storage scheme and how it will fit into your business. There's no date anywhere but the brochure is a great example of 60s typefaces, not to mention language. The recording includes examples of how the data sounds if played on a regular phonograph. Who's up for decoding it? -j
