Description
Control firmware for a washing machine, read from the machine’s chips before it was scrapped.
Provenance
Rescued from a skip outside a former office in Glenstead Springs. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. Independent reads agree bit for bit.
Preservation
