Definition: S-100 bus


A 100-pin peripheral bus that was used extensively in first-generation personal computers (8080, Z80, 6800, etc.). Created in the mid-1970s for the Altair 8800, it was also known as the "Altair bus." Standardized as IEEE 696 in 1983, the S-100 bus was a simple design that was commonly used with the 8080 CPU. See Altair, 8080 and Cromemco.
