Tandy TRS-80 Model I
Tandy · 1977
One of the three machines that started personal computing in 1977, and the one sold through a chain of high-street shops — Radio Shack had three thousand of them, which is how the TRS-80 outsold the Apple II early on. Notoriously radiated so much interference that the FCC took an interest. The expansion interface is the part that goes missing.
