the vector crt signals are too fast by a factor of six or more for
even the best galvos, you'd have to recode the source to add delays,
considering, if this is a vector game, the vector generation timing
and scaling is always partially hardcoded in hardware,so you have a
BIG problem. Also crts don't have blanking points, buffer points,
extra corner points, all needed by even the fastest galvos, and most
vector systems, with the exception of a few that do sliding stroke
writing,(ie charge a integrator to the new point voltage) return to
center in between objects, the return to center is fine for a blanked
electron beam, but it confuses the heck out of the galvos. btw, as
you expand scan size, you need to slow down the scan rate.

galvos have inertia,electron beams for practical purposes dont.


the other way to do it is use a AO deflector pair, but thats
megabucks.


I know the fellows that did laser mame, and its not easy. plus if
your using game code, its a most excellent way to get sued. Laser
Mame passed the points from a emulated game to a pangolin card
that
drove the galvos, and that is probably the best solution. Galvos
limit out at about 700 points in a image.

if its military, like a flight simulator, start he

if thats not fast enough

neos makes a nice 512x512 XY deflector, so does

probably Crystal technology and Brimrose do as well.

none of the mentioned hard drive motors, modified speakers etc will
get you anywhere close to the speed of a true galvo with feedback
I used to earn my living doing vector graphics with lasers.
