This is amusing, considering the 6502 only has 62 opcodes (according to
Western Design Center). :-)
I've examined the machine architecture of the 6502, and well, it's not
really conducive to MachineForth concepts. SOME things apply, but
compared even to x86, it really is most happy with a more traditional
Forth implementation, I think. This is largely due to the fact that
virtually every 6502 instruction affects the CPU flags. It makes things
difficult sometimes.
