The IIfx has special I/O to take the load off the main CPU.
Most of this I/O is incompatible with the chips previously
used in macs, so many assumptions made about undocumented
parts of the machine now break. MacinTalk probably expects
to find the SCC in a fixed location where it isn't anymore.

Happy hacking,
