IMSAI
IMSAI (Information Management Sciences of America, Inc.) was an early personal computer company founded in 1973 by William Millard. The company became widely known for the IMSAI 8080, released in 1975 as a clone and enhancement of the MITS Altair 8800. It was one of the first commercially successful microcomputers and helped popularise the S-100 bus standard.
The IMSAI 8080 featured a more robust chassis, a clearer front panel interface, and greater expandability than its Altair predecessor, making it a favorite among hobbyists and early developers. It was also featured prominently in popular culture, most famously in the 1983 film WarGames.
IMSAI later attempted to enter the business computing market with products like the VDP-80, but struggled against emerging competitors. The company faded in the early 1980s and was dissolved by the mid-decade.
