IBM PC BIOS error codes (was: who built the first 8086/88 based puter?)

Speaking of inscrutable error codes from IBM BIOS, in the big equipment purge of 2006 at work I obtained a number of IBM PC model 350 and 365s. In my various disassembling and re-assembling of pieces amongst these systems to make a smaller number of maximally configured systems I occasionally get an inscrutable error code form the BIOS. Does anyone know if there are manuals for these models online? I tried searching IBM's web site, but immediately got lost in the large amount of irrelevant results. -- What errors? I am familiar with those models. Fairly standard PC, nothing unusual about them. You're looking for the HHM for these computers, but their website has changed a lot since I worked there. DId you try _www.pc.ibm.com/support_ (http://www.pc.ibm.com/support) ? You might also want to look around at service.boulder.ibm.com too.

xxdp RL02?

by jwest＠classiccmp.org

Does anyone have a .dsk image of an RL02 with a later version of XXDP v2? Hopefully that matches more closely the diagnostic manual on bitsavers? Thanks in advance! Jay West

another mysterious chip

by RMeenaks＠olf.com

That is the INMOS G170 graphics chip. Used in the IBM graphics cards. I got the datasheet somewhere in my house :-) I remember AD also made a pin-compatible version of it too...

who built the first 8086/88 based puter?

by Richard.Cini＠wachovia.com

I don't know where in the overall timeline this is but wasn't the Tandy 2000 based on the 80186? It was introduced in 11/83 and ran an OEM version of DOS 2.11. -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Chuck Guzis Sent: Thursday, March 23, 2006 6:33 AM To: cctalk at classiccmp.org Subject: Re: who built the first 8086/88 based puter?

I think the distinction for 8086 may be Altos or one of the other S-100 makers, although Intel may have had a card for the MDS even before that. Bill Godbout had his 85-88 card considerably before the PC. As for the 80186/80286, we were debugging pre-release engineering samples of both chips at Durango (I still remember the bug where DMA activity would clobber the DI register). For sure, the 80186 Poppy rolled out very early. I don't think any 80286 versions were delivered until the Xenix port got finished. But there was a socket on the board for one before that--just nothing to run on it. By the time of the 386, Mobo profiles had pretty much standardized for PCs, so I suspect someone like Mylex may have had the first motherboard, but I don't know if that counts as a "computer". The PS/2 386 boxes were also out fairly early--didn't the Model 50 have a bug that required replacement of the mobo? Cheers, Chuck

AViiON on Intel

by dgy＠DakotaCom.Net

Hi, I'm trying to get DG/UX installed on an AV3700. But, having a helluva time trying to sort out the proper incantation for the boot device. I managed to get things running on an AV3000 some years ago but the 3700 is a different beast. Has anyone here wrestled with these beasts (they have *got* to be the most annoying things to get running! :< ) Thanks for any pointers... --don

Wanted: Ohio Scientific...

by wh.sudbrink＠verizon.net

For those who don't already know, I focus my vintage collection on Ohio Scientific. I would really like to fill out my collection with a C1P-MF Series II, pictured here (sorry if the URL wraps): http://www.technology.niagarac.on.ca/people/mcsele/images/OSIAd-1981PopularE lec.jpg Also, I need the tan/brown metal floppy chassis for an original C1P-MF. Yes, I know that many were sold with the metal/wood floppy unit that usually went with the C4P but I'd like an example of the other model. Finally, I'd like a better example of a C4P metal/wood CPU chassis. I have a 4P with the electronics in good shape but the case is pretty rough. None of the above need to be working, just in good physical shape. In pursuit of the above, I am considering trades of other parts of my collection that are rather rare. Also, I have a small reserve of convenient, wallet sized presidential portraits (but don't get any ideas of ebay level riches). Thanks, Bill Sudbrink

Escon Microcomputer/Selectric Interface System

by marvin＠rain.org

Yes, the box is basically a 6502 microprocessor and support chips, and has no mechanical connections to the Selectric.
