Yeah, there isn't much info out there. One reason, I think, is because these
systems are almost completely proprietary AND they are damned hard to work
on. For instance, if you want to remove the hard drive, you have to
basically disassemble the entire system... and doing that is a real tedious
and time consuming chore. Plus, they are put together in a really funky way.
The motherboard is on one side of the base plate, and the Bus is on the
other -linked via a wrap around ribbon cable. I have no idea what they were
thinking when they designed this system but one thing seems clear; they
wanted it to be as heavy as they could possibly make it.
I have in my hands here, a hard drive/card unit from a 6300, which is very
similar to your 6310. The specs are:
Seagate ST238R MFM drive (10meg) with a matched Seagate MFM controller card
(Rom Version 1.7)
Keep in mind that these early MFM drives required a matched controller card.
Not any old MFM card will work. Another thing to consider is that that these
cards might have additional code in their ROMS specific to the AT&T 6300
series. The 6300 was not IBM compatible so it had a lot of patches and such
for running MS DOS 3.3 for example.
The chances of you finding a working 5.25 MFM drive and card outside of
another 6300 series system are slim. The 6300 is far more common than the
6310 or 6312, so in my opinion, it would be worth it to cannibalize a 6300
to find parts for a 6310.
I don't know the manufacturer of the 5.25" floppy drive but you can bet that
it was an "off" model drive.
I have pics of my 6300 and 6312 on my web site at
