It would probably be worth it to temporarily define one of the reserved opcodes as putchar.

Yes, "temporarily".

It would definitely be a fitting nod to the history of the 6502 (which inspired this processor) to have a variety of incompatible undocumented instructions. Maybe not a good thing, but... fitting.

Video RAM starts at 0x8000.

True, but there's no information on the display modes or the framebuffer format.
