Orchestra-90, also known as Orch-90, was a popular hardware sound add-on for the TRS‑80 Model III and Model 4, and later the Color Computer. It was created and sold by Software Affair of Sunnyvale (originally Santa Clara), California, along with Orchestra-85, the equivalent add-on for the TRS‑80 Model I. It became more popular when Radio Shack began selling a licensed version of Orchestra-90 in 1984.


Like many personal computers at the time, the TRS‑80 Model I had fairly primitive built-in sound capabilities. That changed in 1980 with the introduction of the Orchestra-80, a small $79.95 unit that plugged into the TRS‑80 and could play music with four simultaneous voices over a six octave range. Orchestra-80 was sold by Software Affair, Ltd., a company created by Bryan Eggers and Jon Bokelman. It became one of the best remembered hardware add-ons for the TRS‑80.
