I will look for it... I also have an old book called 'Star Ship
Simulation' published by Dilithium Press...

Sure did...

Yes, it was made out of colored plastic shapes... with a few shaped
metal rods and a number of what amounted to 1/2" (If I remember) sections
of plastic straws which were used to do the actual programming.

The documentation shows the parts, but not to scale... if I had a
real one, I'd try to duplicate the parts...

I remember the follow-on unit, the DigicompII, was not so much a
computer as it was a game of Nim... I got that one as well, but
I preferred the DigicompI
