CROMEMCO was founded by two Stanford students in 1974, Roger Melen and Harry Garland, they lived in the Crothers Memorial hall Dormitory, and used this as the basis of the name for their company.
A university campus was not an ideal place to meet people to advance the business, so in 1976, he company relocated to Mountain view, becoming incorporated in the process.
Initially the company produced cards for the S-100 bus, that were used in the Altair and Imsai machines.
