Yes. It's all over the archives as "Prog 101" and spelled out on the
website. Help yourself.

Not for the faint of heart. I think you'll find the processor to resemble
a MC6801 with pinouts like a 6800 (per Ludis) and set to run in mode 5.

Everything you want to know and more is avail from

Well, almost. You'll need rotsa info on Motorola cpus to do the
disassembly.

Good luck,
