I have one of these boxes. It appears that IBM took another PC case off the
assembly line, stuck in a power supply and a passive backplane. There are
two interface cards, one for the PC and one for the expansion box, connected
by a very stiff cable -- don't recall what's on them but probably buffering
ICs and the like. The cable is about 3/4" in diameter. It terminates in
D-shell connectors but I don't recall the pin count (probably D50). The
stiffness of the cable borders on inflexible and mine pops-out of the metal
shell constantly.

make one using an isa riser card that came with an old 486. do they
connect to serial port or piggyback an isa slot?
They are a box with a passive ISA back plane and a pair of ISA cards
that are connected with a single round cable about as big around as
your thumb. The box itself is styled like an XT (down to the sloping
front).
