This computer has a micro-modem box on a narrow ribbon cable emerging from the back which bears Model #MM-103-9, serial # B2-3542. It has a maximum complement of five S-100 boards, accounting for its slightly greater weight. The SOL Terminal Computer was designed by Homebrew Computer Club president Lee Felsenstein. Although originally intended as a TV terminal, the addition of an 8080 microprocessor and monitor-in- ROM allowed it to accept keyboard commands. It was one of the first machines to have a built-in video display interface and to dispense with the traditional front panel containing many switches and lights.
