Oooh, that has an 8X300 on it. I've never seen one in the wild.
The 8X300 was a stupidly fast (for 1980) Signetics microprocessor. I designed some hardware around it when at Bell Labs in 1986 (which never even made it to the hardware prototype stage).
It ran with an 8MHz clock, and could do an entire instruction cycle (fetch, decode, execute) in 250ns. It had a very simple instruction set, obviously (i.e. RISC).

Very nice processors. And you can fry an egg on 'em. Neil, I'm interested in that board, if you can hang onto it for a bit. (thin month here) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
