When I have it done *to my satisfaction*, of course I will share it.
Actually, if someone else wants to do it while I'm doing bitblt, go for
it, otherwise you'll have to wait a bit.

Yep, a *very* crude one, and a polling keyboard driver (*that* was
fun...)

On the 386 I guess PIC will suck 5-20% depending on the code. I once
messed with gcc's register allocation an crippled it a bit just to see
how much register usage affected speed. That was the results or
crippling one register. I think PIC is out, even though it would be
nice. We have to think of a better idea....

I'm *really* looking forward to getting a decent filesystem. BTW. I
wonder if we shouldn't remove *all* the CR/LF conversion stuff in the
libraries, and just go straight Unix style. The more I think about it,
the more I think a single character EOL is important.
