The SIM8-01 prototyping board was introduced by Intel in 1972 as a low-cost hardware aid for the development of applications involving Intel's 8008 microprocessor. This article traces the SIM8-01's development at Intel and analyzes its impact on the formation of the first wave of worldwide microcomputer activities.

20. When introduced in 1972, the SIM8-01 was far too expensive for computer amateurs. By the time the hobbyists were ready to build their first microcomputers, the SIMs were discontinued and replaced by the Intellec series development systems—even less affordable to hobbyists.
