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
Very nice - good to know and I will check that out next time I'm at Infoage. Thanks Dave! On Sun, May 25, 2025, 08:19 Dave McGuire via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

Is there a 3B2 there?? -Dave On 5/25/25 08:59, John Heritage wrote:
