Video provisions on S-100 frames (was Re: 80 col Apple ][)

by kapteynr＠cboe.com

I soon I got my Altair 8800 working in 1975, I bought a Processor Technology VDM-1 card. (Video Display Module) We converted a black and white portable TV to be the monitor. I believe that the VDM-1 provided the prototype for PC character graphics and extended-ascii "special" characters. I noticed that the Commodare 64, which came later, pretty much copied it, with a few additions. >From memory, I think it was only 64 columns wide (by 32 lines ? ) We modified our VDM-1 with a homemade light-pen attachment. (there is an article in Byte? how to do this). -Rob -----Original Message----- From: Richard Erlacher [SMTP:edick@idcomm.com] Sent: Thursday, January 31, 2002 9:38 AM To: classiccmp(a)classiccmp.org Subject: Video provisions on S-100 frames (was Re: 80 col Apple ][) I'd be really interested in knowing specifics about this, if you have them. I've got several S-100 boxes, and not a one has any accomodation for video signal from an internal source. I did, in the rar distant past, own a couple of systems, at least one of which was from Vector Graphics, that used an external moitor+keyboard combination resembling a terminal, which it wasn't, but most of the S-100 arrangements I've got, including a combination from SD Systems, which uses a video display/keyboard port board not only has no cable that came with it, but simply provides pads to which a video cable was to be soldered. Though I've got this hardware, I've never tried it out, as I've always been satisfied with a serial terminal. Additionally, I've actually never seen a 3rd-party S-100 box that made any provision for video signal to an external monitor at all. The ones I have are all Integrand boxes, so that's not a good example, being from only one maker, and the CompuPro boxes I've junked had no provision for video connectors either.

Screwed again! Property dispo stuff...

by root＠diablonet.net

Hi everyone! I managed to make another trip out to the Univesity of Michigan Property Disposition warehouse. Here's what's up. * Continuing the REALLY annoying trend of people taking off with stuff before I can get to it, the ESV-3 was gone, which really sucks. I hope it went to a good home. * I did, however, pick up that Data General dual floppy disk drive. I made a mistake when originally posting to the list, however - the drive is a dual 5.25 inch unit, rather than an 8 inch unit. I'm not at all sure about the functional condition of the unit, and the model number of the drive is 6030. I paid $10 for it, and frankly, it's free to anyone who wants it. The only caveat is that you really have to pick it up from me, or arrange for someone else to do it in your stead. The thing weighs a ton, and I do not really have the time nor the inclination to lug it to a shipping outlet (I'm a student without a car, and I've forked enough money over to the taxi companies this month already). If the interested party is willing to wait a month or so, I can take it home over spring break and ship it out from there. Be forewarned that shipping will probably be somewhat expensive, though. * I also picked up an HP-IB looking cable with a Commodore logo on it. If I remember correctly, these were used to connect peripherals to some old Commodore systems (I don't really follow them). It looks like it is totally unused in original bag. If anyone wants it, let me know. I pretty much grabbed it with the express purpose of offering it to the list, as old micros aren't really my thing. It's free as well for the price of shipping, I guess. Kind regards, Sean -- Sean Caron http://www.diablonet.net scaron(a)engin.umich.edu root(a)diablonet.net

HP 9000 800/G40 battery?/cable

by csmith＠amdocs.com

Ok guys, The only other person I've been able to contact regarding this HP console cable tells me that there are only 2 pins connected on his cable too, so I'm going to assume the cable -- since it works -- is correct. :) I can still post a "corrected" pin mapping, though. Anyway, on to the next problem. How does the battery backup system work? My understanding is that there's a battery in each PSU, and when you lose power, those batteries will maintain the RAM contents. The machine should then resume in-place when the power comes back. Is this right? Here is why I'm confused: The charging light came on when I first plugged the machine in. It went off a while later. So it seems to think the battery is charged. I tried to test this last night, by plugging the system into a surge bar with a disconnect switch. I booted the system, ran some programs, and cut the power. After about 20 seconds, I applied power again. At this point the machine will boot -- noticing, and warning me that there was a power failure -- and bring the system up in the normal "hey, you didn't unmount this disk properly" fashion. As far as I can tell, none of the processes I'd left running were there. There is a configurable variable in the kernel -- something to do with power failure -- I have tried this twice with the variable set to both 1 and 0. What am I missing? At this point I'd like to find out whether it's likely to be operator error before I go poking around for the batteries. :) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

S/36Doc (skating on thin ice)

by ceby2＠csc.com

Folks -- > I'm working on reviving a 5362 right now. Please reply > off list with whatever persuasion is required to at > least allow me the use of them. I'd be very happy to > scan them all and make them available. While I am all for saving and scanning docs for older computers - I must say that this latest talk about scanning and making public relatively current IBM stuff is scary and dangerous. S/370(ish)s and S/36s are still out there, in suprising numbers. IBM has NOT given any permission for us to make the information public. Please, people, do not make this stuff public until IBM blesses it. They have been turning a blind eye in the classic computing world, but we would not want them to clamp down, would we? Lets wait a few years...anyway, S/36 and S/370 docs are fairly common. Now older IBMs - 650s, 1130s, and the like - are pretty much fair game, and I doubt IBM would really care. S/1s, S/3s, S/7s, S/88s, 8100s, and PC stuff, however, might cause problems. William Donzelli aw288(a)osfn.org I won't speak for other systems, but IBM publishes nothing for the hardware or original software on System/36 or System/38. The only reference they make to it anymore is the emulated environment still available under OS/400. I have a few contacts at IBM, and I've been in contact with their publications people. I haven't broached the subject yet, but I believe IBM like other vendors embraces it's history and will at least tacitly support hobbyists. My own strategy with System/36 will be to create the electronic media, then offer it to them as a _fait acompli_. I'm intending to ask them to host the documents themselves. I don't believe they'll do so on their publication website -- but IBM maintains a substantial forrest of FTP servers it's used for 15 years or more to support it's sales partners and field representatives. That seems a likely place to put them. I'm guessing the real reason why these things aren't available is IBM didn't wish to invest the time in maintaining them. They also wanted to encourage migration. But hobbyist are a new and accomodating market. And I have a certain amount of faith we'll see encouragement from them. First things first though. I actually have to get a hold of the document set. Irregardless of web availability, I'm sure an email in the right (my) direction will yeild results, when there are results to yield :->~ nudge nudge, wink wink, knowwhaddamean?!

Nuclear Data 66?

by vcf＠vintage.org

Has anyone ever heard of Nuclear Data? I found this cool-assed computer today. It's an all-in-one unit (CRT/keyboard/diskdrive/CPU) and is fairly big (say, as big as an IBM Datamaster, bigger than a PET). The coolest part about it is that it seems to be LSI/11 compatible. At least it has a DEC bus (whatever the bus is called that had quad slot connectors). The card cage pulls out from the back and is situated behind the CRT. I couldn't find the processor card because there were too many cables jumbled around. It seems to have a couple firmware cards. I wasn't able to boot it up because I couldn't find the right kind of power cable (it uses one of those oval shaped power cables...I just saw one the other day and now can't remember where I put it). A Google search turns up nothing relevant. I would have snapped a digital photo but my camera is malfunctioning. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
