I think a two computer solution might be easier.  If one can get early
serial on the target machine, then a small romcc program could read
commands from the serial port, execute them, and transmit back the
results.  (I think I even saw an email from someone that did this in pure

Then, a specially modified emulator could run the original bios on a second
machine, forwarding memory reads/writes and io reads/writes through the
serial port to the target machine.
