The rumor back then was the S-100 bus came from someone finding a great
deal on milsurp edge connectors. There were a number of alternatives.

Despite the name, the STD bus wasn't a standard. Sprague Electric had a
severe case of NIH so I designed a bus for them that used a Z80 processor,
memory cards, and I/O cards. You could get away with a lot with 3.57 MHz.
It was fun and they were willing to pay for the project but a COTS
solution would have made more sense.
