Description
Control firmware for a sewing machine, read from the machine’s chips before it was scrapped.
Provenance
Deposited by Millfield Falls Computer Heritage Centre, which had held it unread for years. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. Most of the work survives, but some files are lost. The damage map lists them.
Preservation
