The GAPP chips are available from NCR (Fort Collins). They used the old 3 micron technology. Nevertheless you get 72 cells (a 6 by 12 array) on one chip. Each cell has its own 128 bits of memory (on the chip). You might even get GAPP boards from Amber Eng. (Santa Barbara, California). NCR used to make some toy boards, possibly still does. I hear that newer variations of my invention are produced (with an 8 by 16 array) but I don't think they are commercially available. GAPP stands for Geometric-Arithmetic Parallel Processor. I made up this name to emphasize it's two strengths. It is used in military applications. But besides being practical, it has pure architecture. It's instruction set forms a simple language perfect for theoretical research, like for studies in the computational complexity. (I got Conway's Life in 25 GAPP instructions and wonder if anybody can lower it. Independently, about a year after I got my program they independently had a competition at NCR but got only 30++? result). -- Wlodek
