Not quite industrial, but an interesting early microcontroller application I remember is from around 1977, a music synthesizer keyboard (possibly the first one that was sensitive to how hard you hit the keys) using an RCA 1802 microcontroller.  It acted as a peripheral to an 8080 based "host" -- a PLATO terminal with a waveform synthesizer attached, along with that keyboard.
