Description
Control firmware for a pager, read from the machine’s chips before it was scrapped.
Provenance
Donated by the creator’s family in 2020. The window labels had peeled and the EPROMs had been exposed to light, so each was read many times. Everything was recovered, with a few damaged files repaired from a second copy.
