  This one came out of IBM systems (sorry, I dont recall the actual
models involved here).  These systems were designed to be relatively
low-footprint, with the computer proper (minitower) tucked away
somewhere more convenient.  These cards attached a remote floppy/cd
unit, as well as the kb and mouse (ps2).
  Pentium/Socket7, replacable VRM, upgradable L2 cache (the unit I
have has ".2MB NS 32K x 64 3.3v 66MHz), odd construction.  Used an AT
psu, ps2 kb/mouse, riser card for all expansion slots.
  I had a customer with one of these systems, and they were ok for
their time.  When they upgraded their system, I was given the old one.
 Very handy design if you used the drives alot, but otherwise, it was
just annoying.

  Best wishes.
