If I did it by replacing the BIOS ROM, I'd consider it. The bulk is
more than I really want to deal with (not that it would dwarf a PDP-8/e
or PDP-8/a, but it wouldn't be a portable solution.

It's true - the lowest effort solution is to take a junk PC and let it
do all the work. Not very small and not very power efficient.
