Description
Control firmware for a lift, 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. Independent reads agree bit for bit.
