Swift answering machine controller, model CB-570

Swift Electronics, 1983. Firmware for an embedded controller.

Description

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

Provenance

Deposited by Port Wrenmont Community Archive in 2026. 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.
