A bit output for a speaker seems well worth it, for diagnostics alone.
This project is, like most products, a compromise. We're going
to have to have some kind of ISA bus for expansion, or there won't
be enough people wanting the machine to make it a reasonable project.
I suggest that very common peripherals (disk i/f's, serial i/o,
keyboard i/o, and video i/o) be on the motherboard. The cost
is very close to equivalent, and the software effort is much
improved. You get a more reliable system because the basics are
