I strongly suggest that you get a copy of AT&T's Hardware Reference
Manual for the 6310, comcode 105293534.  This is available from
their Customer Information Center, 800-432-6600 and they take
credit-card orders over the phone.  This book has schematics, and
pin-outs for the connectors, and definitions for the jumpers.

The 6310 is an AT-compatible version of the 6300PLUS.  It was
designed to work with AT-style hard/floppy disk controllers such as
the Western Digital WD1003WA2, which won't fit into the buss
expansion board in the 6300 or the PLUS.  (The 6310 comes with
AT-compatible 16-bit slots.)

No, that UNIX only works on the PLUS.  One reason is that it
requires that the upper 384 kbytes of ram be addressed at the top of
the 16-Mbyte address space of the 80286.  That's where it is on the
PLUS.  The 6310 is AT-compatible, so the upper 384 kbytes of its
first megabyte are located at 1 Mbyte.

The 6310 will support Microport V/AT, and AT-compatible XENIX, as
well as OS/2 and good old MS-DOS.
