What in the world is this thing? Some kind of early parallel or vector 
processor? External? How delightfully weird, except there is very little 
online about it. Did any of you work with one of these? What kind of 
instructions do they use? What is their bus width on the ...uh what? CPUs? 
What kind of addressing modes & size(s) do these use? Why does the one 
reference talk about the 64k RAM they had? Were these standalone machines 
('cause it looks like it goes to a VAX-11 and "LSI-11") ?

This was before my time but fascinating, nonetheless.
