Ultra rare in-depth technical review of the ultra rare PAIA 8700 Computer/Controller. This review is scanned from my copy of Electronics & Music Maker, April 1981. Article written by Dr David Ellis.
The original PAIA assembly/user manual is available from the Cloned Analog Gear website (part1 & part2). A corrected circuit diagram is available via The Old Crow (Scott Rider) website here.
