I don't. I was using the resolution of the only touch screen monitor I knew
about for the AMIGA that works over a serial or parallel port.
I called the manufacturer, they said there was a mistake, x240 should be x400.
Elographics and MicroTouch also make touch screens, but they work over a
serial port or the PC/AT bus. The videodisc player needs the serial port.

I need genlocked output from the 12-bit RGB slot and composite video.
From talking with Commodore, the higher resolution(ECS) you refer to
will NOT work with the genlock. So in a non-interlaced mode the best I can
get is   320x200 with 64/4096 colors or 640x200 with 16/4096 colors.

I was more concerned with the graphics looking good. With the previous
mentioned colors/resolutions available, I'm not sure that's possible.
I will address that question to comp.sys.amiga.graphics .

Let's say, I COULD use the VGA output from the 3000. I know there are 2 or 3
PC/AT slots on the 3000, but don't I need a bridgeboard to use those slots ?
Is the 3000 able to address any PC/DOS boards directly ?
How does the 12-pin RGB output from the 3000 get to PC genlock ?
Someone help me out here.
