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 ?
