This is a stable Version of a 68000 compatible CPU.
It is an adapted Version to use with the Minimig Core.

"compatible" means that most of byte and word Instructions are cycle exact but many other Instructions are faster.
"adapted" means that the synchronous Mode, some bus control signals and the FC Out are missing. They are not needed for the minimig.


circa 3600 LC's on a ALTERA Cyclone II,
circa 2700 Slices an a XILINX Spartan 3,


Tested with the Dennis van Weeren Minimig Core on the C-One Board with FPGA Extender from Individual Computers.
