I think the acorn was a 6502. It's easy to disassemble, if you have
the binary. Electrically, the support chips are essentially 6800
series (motorola). It could be driven (assuming that you have enough
I/O lines) by a parallel port, with (and if) you can provide it with
enough lines (data or otherwise).

I have a fair amount of experience with the 6502.
