I am keen on support for the older Cirrus Logic chips, and the
ATI-Mach-64. The reason is that I have both in hardware, and can
readily test them with LSD at some point to verify PCI bus
configuration, when that gets up, and it's cheap hardware. (Remember
that you must make LSD give you the card IO slots.)

As far as exotic hardware.... Think you could drive two monitors at
different polarisation, and use polarised glasses to get a 3d kind of
effect? Or interlace polarisation? Probably not.... I doubt you can
control light polarisation from standard CRT's, but that idea always
appealed to me. Maybe B&R or G&B or some other color spectrum eye
fooling? (Like the old 3D movie glasses from the 1950s, as depicted in
Also, James, please record what access you need to each individual
card you support, and whether that card has arbitrary physical address
write capabilities that are part of what would be exposed. This will
be important for the stability and security of the system. (And don't
lose your docs for each card. I'll need to make the LSD PCI backends

P.S.: At some point, get around to the cheap VGA graphics, as
discussed? Would you like 16-bit VESA-BIOS support? I could make a
16-bit BIOS segment for that, and get you a few modes that way....
