Description
Control firmware for a boiler, read from the machine’s chips before it was scrapped.
Provenance
Transferred from the backlog of unread media at a partner archive. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. All files were recovered; 40 damaged sectors were rebuilt from redundant data.
