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.

The company produced four systems, the System 0, that ran on a Z80A processor, had 64KB of RAM, and two 390 KB Floppy Drives. The System 1 added a 5MB Hard Disk Drive, if there was a System 2, there is no information on it, but the System 3 had two 8" disk drives, was S-100 bus multiuser, and used the MP/M operating system. It was designed to be built into a desk, or rack mounted.

In 1982, Cromemco also introduced the CS-1H system using a dual processor board Motorola 68000 and Z80.

A sales brochure has the following information.
