Unfortunately, the 4.8 8.24 and 8.24GC only provide MONOCHROME NTSC output.
There is no RCA connector on these cards so you must hack together your own
cable to get the signal out.  You must also set the card to 60Hz (somehow!).

With RGB to NTSC converters running at around $1000, there seems to be a
definite market for a low-cost RGB to NTSC converter.
