I have presented MS-Windows as a given here, but in fact I could also use Linux.
Do any possibilities involving Linux occur to you?
What kind of use do you require here for your app -- is that a one-off
installation or a more widespread deployment?
For a single use your simplest solution might be using similar hardware.
ZLX-E2 is the PMAGD-B or HX+ TURBOchannel option (24-bit DirectColor, no
Z-buffer, using a Bt463 RAMDAC), also known as SFB+ (Smart Frame Buffer+)
after the graphics ASIC. A 5V PCI variant was manufactured under the name
of ZLXp-E2, more commonly known as TGA (I don't know offhand what the
acronym expands to). Both are supported under Linux, using the `tgafb'
kernel driver and a corresponding X11 DDX module.
So you might try this instead, chasing a 24-plane PCI TGA board should be
doable. The board has no VGA compatibility AFAIK so there should be no
odd issues with legacy address decoders or initialisation on non-Alpha
systems -- the board should simply sit there quietly until initialised by
the kernel driver and then taken over by the X server. The DDX module for
the X server might not be built by default for TGA on non-Alpha systems
though, so you might have to do some tweaking.
Just a thought, maybe it'll help.
