Why no FPGA accelerator cards:
the knowledge sandwich
FPGA -lots of people have knowledge and experience
Glue Logic -requires knowledge of both FPGA and 68k interfaces
68k -lots of timing and signal stuff
Not impossible, but very difficult. All this knowledge needs to be gathered and put together to make something useful. It isn't about money. This is a hobby, Minimig was designed basicaly to see if it could be done.
