Corvid jukebox controller, model JJ-470

Corvid Appliances, 1986. Firmware for an embedded controller.

Description

Control firmware for a jukebox, 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. About 81 percent of the data could be read; the gaps are mapped.
