Digging through some old junk, I found my small plastic case with three very interesting chips: An Inmos T800, an IMSAI110-G20S, and an NCR45CG72. I've been able to find datasheets for the first two, but google has failed me on the last one.
So far, what I've been able to find that's even CLOSE to a datasheet is NCR's short form catalog from 1985. That's after I found places that describe (but do not provide more detail) it as a "Geometric Array Parallel processor." The catalog states that this IC is a 6 x 12 parallel systolic array processor, each element containing 128 bits of RAM and a bit-serial processor, along with some other goodies. Basically, it's almost like a teeny little chunk of a Connection Machine CM-1 or a MasPar MP-1. But these chips have me excited, and I want to build something with them! So, if anyone could provide any links to the datasheet for this device, PLEASE let me know. Thank you!
