But that a solution could be to join a male socket and a FPGA on top of that. Much like the 486- or pentium  overdrive solutions for the x86.


For DIL packages OHO Elektronik is already doing that with GODIL. I am not sure if they could be used as a M68000 replacement and how quick it could be. The memory on the board could probably be real fast RAM. The products are sold at trenz electronic.

I think somebody should make a similar board but replace the DIL connection with an A1200 trapdoor expansion connection. I would love that!

I know for fact you can do the byte swap/word swap with the FPGA in real time, but depending on how fast the x86 is it could slow down the operation of the 680x0 emulation.


How do you know if you need to swap or not ? For example a memory copy function that uses 32bit transfers but may be copying strings that may not be byte swapped ?

The only benefit is a bit of ego boosting, but that subsides when reality hits.


Maybe it's just called hobby...
