Should be easy since it doesn't contain any registers and feedback terms.
I don't know how you'd get the fuse map without using a programmer, I'd
just read it like RAM and figure out the terms that way.

I'd use a small CPLD like a Xilinx XC95XX device. They are 5V and easy
to program.

Anybody used Xilinx XC4010E FPGA's ?
and, could I fit a 6502 into one ?

Programming the thing is a pain -- you need about 4 different programming
voltages. I do have the programming algorithm somewhere and one day I
should probably have a go at making a programmer...
