We had similar Precision Architecture machines (in appearance), but the 
monitor and keyboard would have actually been an HP ascii terminal, 
connected via serial.  no video.

I'm not familiar with the 68000 line your links list.

Also no matter about that guess, the second box has disk drives which 
are essential to make it run anything much.
