Today I had time looking at this heavy and thick collection of schematics, notes and stuff.
Just realised that it is from the first half of the 70's. Yet, what exactly is it.
Other than it is for some kind of NCR-Punchcard computer. Someone thought that I might wanted it.
So I took it and just had it sitting in the closet for the last year or so.
By the initial looks of it. I think it is fairly complete, down to the schematics and service reports.
Just too smelly to take a really good and close inspection at this point.
