Someone contacted me about using an FPGA with a RISC core because a
friend and I wrote an Apple //e emulator in ARM RISC assembler. (Great
fun!)

Of course a few short-cuts were taken because back in '95 we were
coding for an 8MHz ARM 2, but an ARM 3 (~25MHz with cache IIRC) ran the
emulator at about 1MHz. Modern ARM cores would do much better.

ARM source for a 6502 core is available if anyone else wants it.

Cheers,
Nick.
