Never heard of this Checkmate thing you're talking about. I saw something about PowerPC as well. You're description making it work felt a little like, "time travel is easy, just plug the flux capacitor into your 23 pin floppy port and press Ctrl-Amiga-Amiga." Lol
Steve Jones was responsible for making the Checkmate 1500 and it was the sole reason that Commodore UK introduced the A1500. I think Commodore may have taken legal action against him, there was definitely some kind of threat made. He did recount the story somewhere on the forums a few years back.
