Heron jukebox controller, model ZR-450

Heron Instruments, 1993. Firmware for an embedded controller.

Description

Control firmware for a jukebox, read from the machine’s chips before it was scrapped.

Provenance

Deposited by Marcombe Computer Heritage Centre, which had held it unread for years. The controller had failed, so the memory chip was removed and read directly. All of the work survives. The repairs are listed in the record’s damage map.
