Can't wait to see Acube minimig 2
This is Yaqube's FPGAArcade Replay expansion 68060 board plugged into the FPGAArcade Replay. The 68060 is a rev 6 68060 which can be overclocked to about 100MHz but they are in limited supply. The chipset core started as the MiniMig core but it is highly customized and much enhanced including AGA support. This is not the MiniMig 2/plus from Acube that will have the Dragonball "68000" CPU. The product is real but nothing is "officially" for sale yet.

As far as I know is Coldfire no alternative because not compatible to 68000. The rest would have to be emulated and that would destroy all performance gains.

Old stock of the 68040 is available today for less cost than the 68060. The old MC68302, MC68340 and MC68360 "communication controllers" could interface with a 68040. They had a CPU32 processor internally and SoC capabilities that are dated today for most applications. This Microsemi 68332 looks very similar to the MC683xx chips. The 68040 makes much less sense today as there are much more energy efficient solutions for 68k performance. Innovasic's Fido is a more modern and useful 66MHz CPU32 processor with SoC features. It's specialized for industrial and embedded control and communications but can be used for other purposes. Supervisor mode and interrupt handling are much different than the 68k but it has fast interrupt handling and context switches (1 cycle in most cases) that would be useful for emulation of 68020 instructions and addressing modes. The CPU32 instruction set and addressing modes are closer to the 68020 than the latest ColdFire. A CPU32 would be very compatible with 68000 code which the ColdFire is not. The best solution for 68020 compatibility, configurability, performance, energy efficiency and cost is an fpga processor. I believe it is possible to have better than 68060 performance from a $30 U.S. fpga and the value of fpgas steadily improves.
