Commodore SuperPET SP9000
The Commodore SuperPET was a computer originally developed for the University of Waterloo in Ontario, Canada. It was a PET 8032 that had added functionality for it to be able to support several languages that were being taught. This additional functionality was supported by either one or two extra boards connected internally that ran via a separate Motorola 6809E processor. As a result, the SuperPET had two switchable modes that were set via a user accessible toggle switch on the right side of the case. The SuperPET could be a normal PET 8032 in “6502 mode” and transformed to multi-language support in the “6809 mode”.
Multiple language support in 6809 mode included Waterloo microBASIC, microPascal, microFORTRAN, Waterloo APL, 6809 Assembler, microCOBOL and a built-in microEDITOR. The MicroSUPERVISOR operating system provided Monitor, Library and serial line communications support.
The focus of the SuperPET was Computer Science labs and Software Development research.
