Tern Companion Animals, 1992. Firmware for electric companion animals.

Description

Behavior and service firmware for an electric canary, made to pass for the real thing at a glance.

Provenance

Donated by the creator’s family in 2016. The chips were read several times in a programmer; one differing bit was resolved by majority. Most of the work survives, but some files are lost. The damage map lists them.
