Description
Control firmware for a boiler, read from the machine’s chips before it was scrapped.
Provenance
Brought to a Lazarus rescue day by a former owner. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. Every sector was recovered on the first or second read.
