IMSAI 8080

The IMSAI 8080 was an early microcomputer released in late 1975, initially based on the Intel 8080 processor (and later on the 8085 processor).

It was a clone of the MITS Altair 8800 computer using the same S-100 bus and is commonly considered to be the first "clone" computer.

The IMSAI 8080 computer ran a highly modified version of the CP/M operating system called IMDOS and was developed, manufactured and sold by IMS Associates, Inc. (later renamed IMSAI Manufacturing Corp).

There were between 17,000 and 20,000 IMSAI 8080 computers produced from 1975 until 1978.

The IMSAI 8080 will be recognised by fans of the 80's blockbuster film 'War Games' as it was the computer used by the main character to hack the US military computer 'WOPR'.
