The making of this computer? perhaps explain why I never had someone wander in and talk
about designing or building a MOTOROLA MINICOMPUTER ....Ed#

  Just made a minor breakthrough; a random usenet
post suggested that the
 MDP-1000 was just a rebadged General Automation SPC-12, and so it is.? I
 suspect the internals of the unit I have (which is badged as an 
"MDP-6650"
  on the rear) are a bit different than either the
MDP-1000 or the SPC-12
 (and I'm no closer to finding answers to my IC identification questions),
 but it at least gives me another avenue to explore...

 (Bitsavers has a few items:

 https://www.computerhistory.org/collections/search/?s=spc-12 

Is this a case of not being able to find the correct TI or Motorola IC
guide or is there something unique / OEM about this one?? I do have some
late 60's early 70's IC guides of these manufacturers that I can check,
original bound paper copies.? Please advise.
