Best person to talk to about 68000 timings is Exxosuk from the Atari ST land. He sells Atari boosters.

These things are bomb proof because they've been designed to work on the very picky STFM. They wont autoconfig on the Amiga of course. The Autoconfig code from my TF530 & TF328 boards is pretty bomb proof and they're in verilog.

There is also an IDE design and clock domain crossing code there.

The issue you will find is you will need to stick a wire over to INT2 on the A500 edge connector (or figure a way round that issue.. i havent yet). And end users screw that up and send their boards back saying they dont work.

If you use my code your project will need to be GPL too.
