Yeah. One PC, components for 5-8 XTs and a working
(the last time I tested it) system board for an XT-296.
Yep, that's it. Once Upon A Time, in a fit of inspiration
intermixed with hubris and ignorance, I came up with what
I think might be a multiprocessor add-on board for an XT.
One Of These Days I just might try to wire-wrap a prototype.
Totally useless, of course, 'cause the system bus bandwidth
is pretty much saturated.

The BIOS would not support a Multi-Processor environment and neither
would the Operating System (DOS).

Oh, I have the source code for an 8088 BIOS and an EPROM burner,
plus I plan to tinker with Minix as the OS. I have a dual-CPU
system board (100mHz Pentium I) earmarked for the software
development effort -- I figured that it was too slow to tempt
me into building a server around it. <grin>
My original machine was an XT that I modded to put 832K on
the system board (segments A, D and E) and wrote an XMS
driver to handle the high 128k as UMBs, allowing LOADHIGH
and DEVICEHIGH (I still have it and it still works).

Sometimes I think that M$ and the chip makershave a sekret
agreement: each new version of Windoze requires enough additional
CPU cycles to warrant an upgrade. The upgraded systems have so
much excess power that M$ can add even more bloat and cruft
to the next release of Windoze. The hard drive manufacturers
have *got* to be part of it, too.

You are absolutely correct. On the other hand I resist upgrading until
either my hardware goes blooey or a game that I simply must have (very
rare) requires it or (far more likely) someone takes pity on me and
donates some hardware in my direction. The only upgrade to an OS
occurs when I get a magazine with a new version of Linux on the
CD/DVD. Win98 is starting to annoy me greatly but since most games
require Windoze at the moment I'm stuck with it.

This "sub-thread" is so interesting I had to reply. In my situaton I
have a dual boot
system. Win98SE on a 40Gb HDD and WinXP-Pro on a 6.4Gb HDD. Since Win98SE
is tweaked and working like a good oiled machine I put XP on the smaller
HDD to get
used to it. I like you David won't upgrade till It's absolutely
necessary. Having said that
I'll be purchasing another HDD to install WinXP-Pro onto, now that I
know it's ins and
outs. Must say that XP is more stable than Win98SE, and "seems" to run
more smoothly.
This is a non-SP version of XP, I'll probably be in for a headache after
installing SP-2..
To give you a clue as to how behind the times I am I'll share some
system specs.
Aopen AK77-600N mobo;
AMD XP2200+ cpu;
512MB PC3200 DDR Ram;
ATI 9550 vid card with 256MB vid ram;
Sound Blaster Live 5.1 Digital sound card;
Maxtor 40Gb HDD;
Quantum 6.4Gb HDD;
BenQ 16x DvD ROM;
LG 52x32x52 CD burner;
All this in a RaidMax Cobra case with 450 watt PSU.
Once XP is installed on the new HDD and Win98SE erased from the 40Gb HDD
my old pal Linux will occupy its sectors. The 6.4Gb HDD will be retired
to storage
and emergency backup if needed.
