IMSAI 8080 Microcomputer, Used with Home Built Interface and IBM Selectric Typewriter, Assembled in 1977

Summary

The IMSAI 8080 was a clone of the Altair 8800, the first mass marketed personal computer. It was a popular "kit computer," requiring assembly and programming. With no keyboard, toggle switches allowed input and LED lights signaled output. This could be modified using an IBM I/O typewriter. The donor, O.S. Narayanaswami, was a mechanical engineer interested in the educative power of computers.
