The '''Altair 8800''' was an American [[8080]]-based microcomputer introduced in 1975 that is considered the first widely popular home computer. It was sold in kit form and fully assembled and had a characteristic front panel with LEDs. The Altair mainboard had no ICs at all, just S-100 bus (100-pin) edge connectors, so e.g. the CPU and memory were on separate cards.

In the beginning, an Altair was usually controlled via a 110-baud teletype (usually with a punched tape reader and punch for saving and loading data). Later there were also 8" disk drive adapter cards and graphics cards that could show color graphics on a screen.
