I think it is probably possible, but it is just too much easier to get a
keyboard and a monitor. There is arcane knowledge in the making of the boot
ROMs :-).

There is a keyboard (unbid upon) for $10+$10(shipping) on eBay as I write
this.

I also seem to recall finding a description of the pinout info needed to
connect a monitor somewhere on the net.
