  Does anyone know much about these? I picked up TWO of these cards today
and each one has 144 NCR45CG72 ICs on it. It looks ike EACH IC has 72
microproccesors in it. That makes a total of 20,736 processors!!! Here's a
bit that I found while searching the net. IN FACT, these may be the exact
cards that this guy is referring to since much of the stuff that I find
does orginate at MMC.

  9. Geometric Arithmatic Parallel Processor {GAPP}, a real time vision
recognition, dynamically partitionable, dynamically fault reconfigurable,
array processor (SIMD) for Martin Marietta in Orlando. Each IC contained
72 microprocessors, composed of a single TCU and multiple ALU-register
sets. Array grows in X and Y dimensions to match a required image array of
pixels matrix, and decimates in time to allow fault reconfiguration and
price/performance options. First successful SIMD VLSI. First successful
real time image recognition. Responsibility included addition to
instruction set {If then, case, etc based on if any, if all, if none},
redesign for performance enhancement, and design of fault reconfiguration
switching at internal IC level and external array coordination.
Non-classified version is the 45CG72 from NCR.
