I wouldn't be surprised if the Foonly was involved in TRON.
TRON was a Big project, costing over $18 million and involving
no fewer than three CG companies. Information International Inc.
was indeed one of the companies and July-1982 was the movie
release. If the Foonly was at Triple-I before then, then its a
good bet it was involved. I think one website said that III sold
its Foonly in 1984 so theres a good chance of date overlap. There
sure were other computers in it too, but the F1 may have been the
most intriguing.
