Anyone know of a RGB (old CGA) output card, PCI or ISA

I am searching for a suplier that has a PCI/ISA card capable of producing
RGB outputs just like the old CGA cards.

The other requirement is that more than one can be put into the same PC. (or
a card with multiple outputs)

I've read that this could be done with some VGA cards, but this varies from
chipset to chipset and I need a "plug in solution"

ISA cards could be used to support older systems, and PCI cards would be
used in new systems.


Thanks in advance,
James Little

All display cards output RGB signals. CGA had 2 levels for each colour (ON,
OFF) plus a common intensity signal (16 colours in all), EGA 4 levels (64
colours in all) and VGA (and DVI) near infinite number of levels and thus
colours.

All OSes from 98 up can control 2 display cards as standard. A number of
manufacturers made quad display cards (Matrox etc.). Some allow up to 4 of
these to be installed simultaneously thus 16 monitors can be driven from a
single PC.
 
Thanks very much for your reply, but it looks like I need to re-state my
problem.

Yes, I understand that win98+ support multiple VGA cards. Yes, I understand
that
VGA is RGB. I'm not looking for VGA output, I'm looking for CGA(compatible)
output.

What I'm looking for is a card that will produce a RGB output exactly like
the old CGA cards.

TTL output... Digital stuff.

Not in PCI... You'd be lucky to find any working ISA ones these days.

It would be easier/cheaper to have a card designed, since CGA is a
relatively simple circuit. (fixed frequency, digital output, etc.)
