Onyx washing machine controller, model EL-860

Onyx Electronics, 1984. Firmware for an embedded controller.

Description

Control firmware for a washing machine, read from the machine’s chips before it was scrapped.

Provenance

Deposited by Redcombe Bay Computer Heritage Centre, from its own collections. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. A handful of files survive, from a much larger whole.
