I used to have the Technical Reference manual for the AT&T 6300. Sadly,
it got lost in a move, it seems. It had schematics, the BIOS listing,
and all the details and stuff. The 6300 (I once owned one) can be a
frustrating machine, because it is NOT a clone machine. You can't put
high density drives in it easily, for instance. It's big selling point
was being an 8086 machine in the era when everybody used 8088 machines.

I am intimately familiar with the 6300 because it was my first PC, and
my only PC for 5 years until I went to college. I upgraded the BIOS and
DMA controller so I could run a later version of Microsoft Word (the DOS
version, not the crap windows version), I cut a hole in the case to add a
3rd 720K floppy drive, bored out a hole to add a headphone jack, replaced
my 8086 with an NEC V30, added an 8087, and a hard-drive-on-a-card.
Short of replacing the video card (which was ironically much harder to
do properly than all of the other things I just mentioned), I tricked
that thing out years before adding blinkenlights to cases was cool.
I even found a lower DRAM refresh rate that didn't lock up the
machine so that I could get an additional 10% out of it.
Needless to say, if anyone has questions on an AT&T PC 6300 (or an
Olivetti M24, which is essentially the same thing), I'm your man.

Nice. I never owned one, but I saw plenty on the scrap heap... nice
source of Micropolis 1335 MFM drives that can trivially be turned into
RD53s after reformatting. :-)

Hot damn! Any more where those came from? :-)

Got a pinout conversion for a display cable? I know at one point I
saw that On Teh Inturweb, but I didn't print it and the link is dead.

Yes but some pins won't convert because they handle AT&T color display specific
things (like degauss -- scared the living shit out of me the first time I ran
the diagnostics and it said "Degausing monitor..." and sure as hell it did):
AT&T PC6300
Connector: D25
1. horizontal sync
2. ID0 (monitor id)
3. vertical sync
4. red
5. green
6. blue
8. nothing
9. nothing
10. ID1
11. Mode0
12. nothing
13. -Degauss
14-21. gnd
22. nothing
23. nothing
24,25. +15V
for a monochrome monitor ID0 and ID1 are open
for color, ID0 is 0, and ID1 is 1, probably 5V, not 15
That's all I have, hope it helps. I don't have it in front of me but I believe
the model number is AT&T 53D410.
BTW, I forgot to mention in my last post that I still have said AT&T. I can
take a picture of my modded case if anyone is curious.

As XTs go they ran quicker than a 5160 just simply because of the 8086 and
16 bit memory, the V30 made things even better.
I don't know why but around here they rarely ever retained their original
monitors, back when an XT based system was still viable for daily use most
of the ones I saw had Taxan Supervision monitors hooked to the original
video card with a custom
cable. Most had the 12" Taxan Supervision IV, but there was also a 17"
Taxan Supervision 770 (I may have the model wrong, but it was definitely
TTL RGBI at SuperCGA resolution, not a Multisync or SVGA).
I did similar tricks back in the day with an Amstrad 1640, which was in
someways more difficult to work with as it had onboard video, and the power
supply was in the monitor. It did have a 640x200x16 color mode before EGA
though (though a version with EGA did come out later). Would have been a
nicer machine if it wasn't stuck with such an awful keyboard and monitor,
though I guess it's to be expected at that price. One company even came
out with a 386 motherboard to fit the oddball case. Being stuck with the
1640s EGA display kind of doomed it though. If I found one I'd be tempted
to stick one of those 486 upgrades in it.

Sweet! How I would have died for a 17" monitor in those days. The flyback
transformer blew in my color monitor twice, maybe that's why they were replaced
so often? My monochrome AT&T monitor (very curious thing -- drew its power
from the DB25, had no power cable) never failed.

do you know anything about a Z-8001 card, that should have been available
for the M24 ? Does this one really exist ?
