Hey folks - I was just curious if anyone had ever laid hands or if we've ever exhibited a Bellmac 32 processor (system)?
Looking at specs, it may have been the first 32-bit microprocessor that was pipelined (one 32-bit instruction per clock). The chip also had a decent # of registers for 1980 (16 x 32-bit registers).
This is the processor used in the AT&T 3B series systems. We have several 3B2s at LSSM (including one running on exhibit, up on the second floor) and I have a couple of my own at home. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
