Because ISA sucks? If I had the time & a backer to do this, I would use a PLX9050, some small SRAMs, a 68EC000 and a 16650, and the reasonably-public-domain VGA BIOS that comes with BOCHS. > This would work with standard motherboards... > > (I'll buy one or two if you make them !) You'll have to negotiate with Jordan for my time, I fear. Too many cookies in the jar right now. 8( -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\
