     Wow, nice
machine! :-)  The ST506 MFM interface maxes out at
 160MB...those are probably ESDI drives.  And if they are, I'm
 jealous. :-) 
 Could be ESDI... the 'boot monitor' (excuse my lack of knowledge of proper
 terms) calls them RA81's (?!?!?).  The connectors look like ST-506, which
 is why I called them that.  I didn't bother looking up that board when I
 'ripped' it apart (very carefully) for cleaning.  Thanks to Gordon, I'm
 gonna be getting a QT13 pertec controller, which will replace the TK50
 controller most likely.  Ahhh, 9 track tapes. :) 
 
  SWEET, an ESDI controller that does MSCP.  Very nice. :-)
  Any idea if I could put another QBUS KA650 card in
here and make it
 dual-cpu? I'm doubtful, but it'd be cool to try I think. 
  Nope.  These are uniprocessor machines.  I believe there was a hack
long ago that allowed the use of two KA630 boards in a system, but it
didn't go very far, and I don't think it's possible with the KA650.
