Hi David,
Wheels seems to have replaced Geos. Or rather it was a later, enhanced version of it. Both Wheels and Geos required RAM expansion to run properly and so it required a beefed-up Commodore system. I believe this all happened in the early 90's. Someone can correct me here.
Do you have a Commodore floppy drive? Send me a PM and we'll discuss...
