Commodore SuperPet (1981)
The Commodore SuperPET was developed by the Computer Systems Group to meet the need of a more powerful computer to run the sophisticated programming languages developed by CSG for use in teaching Computer Science at Waterloo. The unique feature of the SuperPET is that it has 2 complete "brains" - the original 6502-based board that came with the PET and a 6809 16-bit board that was added in to run the software developed at the University of Waterloo.
