Description
Control firmware for a washing machine, read from the machine’s chips before it was scrapped.
Provenance
Bought as part of a box of disks at an estate sale and donated anonymously. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. About 71 percent of the data could be read; the gaps are mapped.
