Zonn's latest hardware description talks a bit about the color conversion.
Since I have to do clipping now, looks like i'm just going to implement
the whole thing now with a uP and two DACs, and do the whole thing in
software. It does have the advantage that you can use it as a test pattern
generator, too :-)

My current thought is to have two 12 bit input ports, and have the uP
watch the state of the start, end signals and an intensity port.

One thing I was wondering, Zonn, is if the 12 bit start/end values are
ever not at the endpoints of the vector being drawn. Do they ever
send endpoint data farther out than the actual line end, and use the
line timer to clip to the visible endpoint.
