It's a normal TV rate (that is, 15.7kHz horizontal,
60Hz vertical) RGB
analogue monitor.
Matrox cards (including 220, G100, G200 and G400) have a fully
programmable dot-clock, so they should be able to drive it. They'll drive
a Commodore 1080, which is also a TV-rate monitor -- I just tried it.
Of course, you won't get a valid display until the OS comes up and sets
the video mode. I believe there's a tool to flash the video BIOS so it'll
power up in the desired mode, but then you won't be able to use a
VGA monitor with that card any more, unless you flash it back.

Is it possible to hook this thing up to a PC? Is
there anything I need
to bear in mind when configuring X?
It will not sunc to nromal VGA frequencies.
Period. I cna't think of a PC
video adapter that will easily drive it, either.

This isn't a problem - what I'd be using it for would be either a
secondary head for video playback, in which case the card wouldn't "wake
up" until I started X, or as a monitor on my MythTV box - which is alway
s running X anyway.

I seem to recall hooking a Matrox board up to a TV in the past (as part of a
homebrew music library system), so it'll definitely do TV rates OK. As others
have said, the usable resolution isn't anything wonderful, though.

I believe that the older Matrox PCI boards (e.g. the Millennium) will do SOG -
they were the preferred choice when it came to driving big SOG-only
workstation monitors from a PC.
