A microcomputer built in 1981 that has gained sentience over many years. A college sophomore (name redacted) in 1981 wrote an AI intended to self-evolve over time; after a few months, he got bored and left the machine plugged in in his garage for five years. In 1988 the AI attempted to transfer itself over a land-line modem into a Cray supercomputer; the attempt was cut off, traced, and the unit was seized by the Foundation. The entire AI resided on a well-worn cassette tape.
