The interrupt stack frames are >> different, so you'll need to path the OS. Already been done for the Amiga. The OS detects and works correctly with any of the 680[0123]0 processors. Software that does floating point operations in the system-approved manner also get 6888[12] suport if the chips are there. As an aside, 2000 owners probably won't be interested in the chip - they're better off going to one of the CPU slot '[23]0 boards, so they'll be able to use 32 bit memory as well as the faster processor. Since that isn't an option on the 500, the 16-bit version of the '[23]0 would be an attractive option.
