 I have a Grinnell framestore somewhere. I must dig it out and see if I
 can get it working. It's a _large_ rackmount unit with PSUs in the bottom
 and a rack of large PCBs at the top. I think mine might have the video
 input option as well. 
 
LARGE rackmount sounds familiar ;-)
Big PCBs, tons of ICs. I don't remember anymor, but it was something
like 512x256x8 resolution. Amazing at this time ;-)
  IIRC, they would connect to a PDP11/VAX,  
Was on one of ours PDP11.
