Dual Props for Video Work...

cbmeeks

So I have this crazy idea to use two Propellers for some VGA video experiments. Something similar to the ANTIC & GTIA of the Atari 800.

Has anyone here done anything like that? Meaning, has anyone used two (or more??) Propellers to generate some video hardware?

I know a single Propeller can do some amazing things with video. Just wondering what (if anything) using two would get you.

Seems like it would be a nice way to get some extra RAM, more sprites, etc.

Thanks!

...but I have no idea where to find the schematics and the software... :-(

Holy cow!

That's really impressive. I wonder how it was wired up? Also, that looked to be NTSC.

Also, correct me if I'm wrong, but could you not run two Props and get 4 bits per color if you used different resistor values for each Prop?

That would be 16 shades each for a total of 4,096 colors?
