has anyone ever even seen a Canon AS-100?

by chrism3667＠yahoo.com

its an all-in-one ms-dos (not pc) compatible, like a Lisa but more square. Can anyone suggert a strategy for finding something exceedingly dopey and uncommon? Viewable on old-computers.com. Japanese computers in general intrigue me, but many just werent sold here, at least not to any great extent. The AS-100 was, but apparently not too many. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

repairing early HP calcs

by melamy＠earthlink.net

just a note... CPLDs are easier because the EEPROM config is inside the chip (no external hardware and an easy to use interface). The cost of this is available logic density though. You will always get more FGA logic space available then you will with a CPLD. Of course, you can always add more CPLDs, but one FPGA and a 8 pin dip eeprom is less PCB real estate. best regards, Steve Thatcher -----Original Message----- >From: woodelf <bfranchuk at jetnet.ab.ca> >Sent: Dec 19, 2005 2:26 AM >To: General Discussion at null, On-Topic and Off-Topic Posts <cctalk at classiccmp.org>, null at null >Subject: Re: repairing early HP calcs > >Chris M wrote: > >>I dont own any.

Sun Open Firmware - insiders?

This seems like a good time to tap into the collective knowledge on this list once more... I have a question regarding Sun OpenFirmware that's been bugging me for some time now. I'm still struggling for a setup that allows a Sun to netboot off a Windows 9x PC (just get a bootstrap, no fancy NFS exports required). I'm making do with SuSE Linux 7.0 dual-boot right now, but that's not it. What I'm imagining here is to have a look at the code that is responsible for the netbooting operation of the Sun. Why does it have to obtain the machine's IP, that of the tftp server and what else via rarp? I'm by no means a Sun expert yet, but as I've understood it, you can define your own FCode commands and store them in NVRAM, so one could modify the boot code to use parameters stored in environment variables, either if a flag "use-stored-IP?" is set or as a fallback if there's no rarp server around. I've already got myself a Forth book and the FCode manuals from Sun, and I had a look at some commands with "see". "see" however often spits out hexadecimal codes in parenthesis amidst of Forth words and I've yet to understand what they mean; the manual addresses the problem only far enough to tell that this doesn't happen if words are defined with the "headers" directive. If somebody has been involved with FCode stuff far enough to give me some initial guidance, please contact me. Thanks in Advance. Yours sincerely, -- Arno Kletzander Stud.

Oldest machine (was: Re: Good haul of old pc stuph)

My PDP-8/E from about 1972 won't even be close to the oldest, but it is running. Running right now, in fact, though I think it has an interrupt problem, with an RX02 and an ASR33 (which is probably older than the -8 is). Apart from that I have a Motorola MK6800D2 from 1975, a PDP-11/03 from 1975 or '76, and a KIM-1 designed in 1975 but probably made about 1977. -- Pete Peter Turnbull Network Manager University of York

Not TS 2048, TC 2048

by alhartman＠yahoo.com

As I was sitting here thinking, I remembered that the Black versions of the TS-2068 had a different name than the Timex/Sinclair Versions... The Black unit with the Spectrum ROMS was the TC-2048. The TS 2016 and 2048 were never made. I think the savings in the RAM chips didn't make sense in the additional costs of changing assembly lines, and stocking different units. There may have also been a TC-2068 that was the same as the TS 2068 with the same ROM as the TS-2068. But, the TC-2048 used a Spectrum ROM for sure...

TS2048

by alhartman＠yahoo.com

I know this is an old message, but TS 2048 Computers WERE made by Timex Portugal. Zebra Systems, Inc. had a couple of them. But, I don't think we ever sold them. They also had black cases like the Spectrum, and I think had Spectrum ROMS as well. It's well over 15 years, so my memory is very fuzzy.

DOS Compatable OS

by mokuba＠gmail.com

I'm rather bored, so I thought I might try and hack together a small project OS compatable with at least DOS 1.x or similar, is there any decent resource for information on dos compatability and how to achieve it, or is it left as a reverse engineering exercise for 'the reader' ? :)

Intel USB chip

by cclist＠sydex.com

Hi Ethan, Hope you're keeping yourself amused down there! At any rate, the trick to finding information on the Intel USB chip is knowing the shorthand used to talk about the darned things. Since they're not in production, this is becoming a lost art, it seems. Try googling on 8x930xx - you'll get a number of good hits, including the complete schematics for the Intel USB prototyping kit. If you want chip docs, try googling on 8x930ax and one of the hits will be: http://www.suid0.net/fhtw/doc/specs/ic/bridge/i8x930ax.pdf which is the user's manual for the chip, all 16 chapters and 4 appendices of it. Whatever you discover, let me know--I still have most of a case of these things... Cheers, Chuck
