I just skimmed the Wikipedia entry for the Cromemco [a]. Apparently, the Cromemco computer was known for its reliability. That was not my personal experience. However, I was wrong about the bus voltages. The S-100 bus [b] had bulk unregulated +8 Volt DC and ±16 Volt DC. It was an oven mounted with floppy drives!

Cromemco, S-100 Bus industrial computer

True stories about technologies I've used over the past fifty years. From 4-bit, Intel 4004 microprocessors to the marvel of op-amps to building an interface to an HP-3000 in a rat-infested animal feed company.
