Hi Paul,
  I think you mean RX11. 
Ah, yes ? I typo?d that, thanks!
  Isn't the BC05L-15 folded up in the case? Or did
they put a short one to the back of the box?  I can't remember now. 
I?ll have a look to remind myself when I get downstairs later today.  IIRC, everything is
brought out to D-shell connectors on the back of the box?
  Which are you on located? I know someone who was
looking for a box last year. 
I?m in Oakland, CA.  I?d gladly pass the box on to some other collector if I can find
rails.
  Are they the old Calcomp cast aluminum, or the newer
DEC 70 class drives? The DEC ones
 can sometimes be converted to RX02s. I think the older (RX01 only) were the M7726 and
M7727. 
Will check and post back.
   Thanks!
