Interesting. Any idea how that might be applied to an analog graphic generator?

It sounds like the driver they use is a digital driver (each point is plotted).
I'm sure the galvo's will follow the analog signal (of Star Castle let's say)
just fine. I'm just wondering how one could calculate the number of "pseudo
points" in the analog line to determine whether this system is fast enough for
arcade use. I could guess by setting up the Star Castle screen into 1600x1600
points (like there driver does), overlay Star Castle and count the points
crossed.

Certainly they must have some limits, could it really keep up with 30,000
randomly placed points?? Seems unlikely.
