A Penny &
Giles 7000D double QIC drive.  No idea what that conencts to. 
 If it's anything like the 7100 single-drive unit I have here, it has
 an RS232 interface and is designed for use in data logging systems. 
 
That sounds right.
   Finally, one
piece of DEC kit I didn't mention last time is the Magtape
 drive.  This is the sort that takes up the top 18U or thereabouts of a
 rack, but doesn't go very deep.  I've been sorting through my Unibus
 cards (some of which are taken, but others may appear here), but I have
 no idea what cards would drive this tape machine.  Can anyone help? 
 Not without some clues, like a model number... 
 
Oops.  TU16, I think.
Philip.
