I don't need to, I have both. I have used an 8032 to test the parts for the SuperPet, and they are compatible. The SuperPet is an 8032 with one or two (depending on the version) boards added. See the schematics and parts lists at funet. The only significant difference is the SuperPet uses a 6502A (presumably to allow for the extra time used by the additional circuits). The extra circuit boards just plug in. The main bus is extended by a ribbon cable connected to the bus connector on the right side of the 8032. The 6502 on the 8032 is removed and a plug connected to a ribbon cable connects the processor lines to the Superpet board where the lines are swithced between a 6809 and a 6502A. - This message was sent through the cbm-hackers mailing list.
