Recreates the 16 MHz 68030 MicroMac Performer accelerator for the Macintosh Plus, SE, and Classic, with an optional 68882 FPU.

For this system (exact model): The project explicitly targets the Macintosh Classic, but operation remains untested and the maker has not found a socket that mounts securely over its PLCC CPU. Treat this as an experimental build path, not verified support. U7 is required and SJ2 must remain open.

Operation has been tested in the Macintosh Plus and SE, but not in the Classic; the maker has not found a socket that securely fits over the Classic's PLCC CPU. Host-specific U7 and SJ2 settings are mandatory. GAL16V8-15 and PALCE16V8-15 parts are tested, while ATF16V8 and other speeds are not.
