Micro Instrumentation and Telemetry Systems

The article explores the history of Micro Instrumentation and Telemetry Systems (MITS), the company that created the Altair 8800, widely considered the first personal computer. It details how MITS started building electronic kits for hobbyists, such as calculators and model rocket telemetry systems, before creating the Altair in 1975, which sparked the home computer revolution.

Background

- MITS (Micro Instrumentation and Telemetry Systems) was a 1970s Albuquerque company best known for the Altair 8800 — the first commercially successful personal computer kit, launched in 1975 on the cover of *Popular Electronics*. - The Altair 8800 used Intel's 8080 CPU, came as a bare-bones kit with switches and lights, and sold for $397. It inspired hobbyists — most famously Bill Gates and Paul Allen, who wrote a BASIC interpreter for it and then founded Microsoft. - MITS was founded by Ed Roberts, an engineer and entrepreneur who originally made calculator kits. When the calculator market collapsed, he pivoted to computers. - By 1977, MITS was sold to Pertec Computer Corporation. Production of the Altair line ended shortly after, and the company faded away. - This history matters because MITS essentially launched the microcomputer revolution and gave rise to the PC industry as we know it.
