Several years ago, I made a CPU exhibit for MARCH mostly demonstrating how the pin count went from 40 (Z80, 8086, 6502 ...) to 64 (wide-body 68000) to hundreds (Pentium, Pentium-Pro, AT&T 32000) to a thousand. It's the "tyranny of numbers" all over again: too many pins to casually prototype (particularly the dreaded ball-grid-array). I never completed the accompanying chart with other stats: year it was introduced, word size, number of transistors, line width, die size, clock speed, CMOS/NMOS/PMOS). I was hoping to correlate it to the systems that used the chip and how so many mfgrs were in the game, particularly with the homebrew & demonstrators (RCA, Motorola, MOS, Zilog, Intel ...) Adam found it in the warehouse, so the exhibit is jump-started! -- jeff jonas
