Anyone seen, done anything with, heard of the Motorola MC14500B industrial control unit? It is pretty much a one bit computer, 16 instructions... Made as a replacement for relay logic. Looks like it would be the heart of a simple computer or could be used as the microcode controller for a more complex design. I've only found a couple of projects using it on the web, a KYTRON 4 "robot" and a chineese experimental board... I've found a 1977 book for the chip on eBay and am looking forward to receiving it... Functionally it seems like an early, scaled-down version of the AM2910...
The chineese board uses the MC14500B as a controller, MC4040 as a program counter, 6116 RAM (only 256 bytes used), MC4099 as an output latch, MC4512 as input register, an unnamed inverter as glue logic, and a MC4011 as the clock... also quite a few LEDs so one can witch execution states, nad a couple banks of DIP switches for input and programming...
