  A most interesting find was unearthed this afternoon,
a DG Nova 3 with
 it's CDC platter drive! Not knowing much about the Nova series of
 computers, exactly what would be required to make it work? 
Nice find :-)  I don't have any practical advice or information, though :-(

  Also found was a home-built Q-Bus PDP-11 with RX50
drives, a M8192 CPU
 Module (What -11 is it?) an RQDX3 controller, a DEC card labelled M7546
 and a card labelle "CTBC Computer Plus 1986" with a  connector that leads
 to a homemade switch a LED setup. 
As you may have discovered, the M8192 is a KDJ11-AA, ie an 11/73 processor.
 If it has -YB marked on it, it's an -AB version, which can accept an FPU,
and if it has -YC, it should already have an FPU.  M8192's were commonly
sold as OEM boards, or as upgrades for 11/23 systems.

M7546 is a TKQ50, ie the controller for a TK50 'CompacTape' cartridge
drive.

Sorry, I can't help with the CTBC card.

I assume it has some memory and an SLU?  And a card with a boot ROM?
