Some of he Power chipset Macs made the migration through 8.xx to 9.xx to 10.0 and even, I believe to 10.4. I do not believe any of the 68xxx chip machines made it past OS 8. And certainly not to OSX. But the first few editions of Mac OS X came with a second environment called Classic which could run applications from earlier days. Regardless, I doubt a Performa could manage it -- the chip was too slow -- aand the early 68000x series were even slower (Classic, Lisa, Mac II)
