Mosaic pipe organ controller, model RE-270

Mosaic Electronics, 1994. Firmware for an embedded controller.

Description

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

Provenance

Deposited by Three Rivers Retro Computing Society, 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. Every sector was recovered on the first or second read.
