IMSAI 8080 computer kit (assembled)

Designed
The IMSAI 8080 computer was released in late 1975 just a few months after the release of the Altair 8800, regarded as the worlds first microcomputer, making the IMSAI the second. It was essentially an improved version of the Altair and can conceivably lay claim to being the first microcomputer clone.

This type of small kit form machine was realised, created and marketed at this time because of the microprocessor - the electronic circuitry required for the arithmetic and logic functions had …

Production

Notes

This microcomputer was designed by IMS Associates Inc in San Leandro, California, USA.

Utilising the S100 bus standard the IMSAI 8080 was a copy of the design of the Altair 8800 the worlds first micro computer. It is based on the Intel 8080 micro processor chip.

The IMSAI was sold as a kit and was therefore constructed by its owner.

The IMSAI was produced from 1975 to 1978.

History

Notes

The IMSAIs were commonly used by their owners to learn about computing. As more processing and memory capacity was added to the IMSAI computer range they became capable of more complex computer applications, particluarly in laboratories and small commercial software developers. John Haymes applied his IMSAI in the development of programs and in streamlining the organisation of his work practices. In 1978 the IMSAI kits were retailing for US$649.95.
