	Yes, get it working first, optimize later...

	I have written a driver for nanoX over the weekend (it doesn't quite work yet,
we had two NBA playoff games to win) that implements native (that's right, no
bios required!) execution on the above ** hardware.  The driver is compiled
for one of the three modes.  I do call the bios to get the native graphics rom character
set address right now once, but that will go away when loadable fonts are implemented.

I am interested if there's anyone on this list who has native mode code for
other screens for the above...

Does anyone want a DEC Rainbow?  There's one in the basement with a 5
MB hard drive (maybe 10 MB?) and dual 5 1/4" floppies.  Lots of
software (mostly CP/M IIRC) including Zork I :-)  It worked the last
time I tried to boot it.

It's my parents', not mine, but I think they'd be willing to send it
to a good home at cost of shipping.

Nah, I already got two....  I have about 350 disks with mine, but I
don't think I have zork. :-).
