Propforth with VGA question

Just got version 5.5 up on the Propeller Proto Board. In a previous application, I wired the Proto Board to use pins 12, 13 & 14 for VGA output to a small TFT color monitor. What I can't quite figure out is how/where to modify vga.f (in Extensions) to work with these pins. Assuming vga.f will give me the same color output I had in the previous SPIN application ... !?

Thanks for any help!

    Can you provide more details? Those three pins look more like TV output to me. VGA usually drives an 8bit bus (2bits each for RGB and sync).

    I think you've reminded me of something ... other than trying to do technical stuff at too late an hour! :)

    It might be TV Text that I'm trying to bring up, rather than VGA!

    How is that done with PropForth?

    Thanks!

    I'd have to check (may take a bit). So are you saying you had TV output before with an earlier version of Propforth?

    Update: From a quick glance, there doesn't seem to be a TV driver in the 5.5 package.

    The previous application was created with SPIN, not PropForth. This will be my first attempt at anything with PropForth.

    I've had a chance to check my previous configuration and what I am looking for at this time is a TV-text capability from PropForth. Has this already been accomplished?

    PropForth may have never supported an NTSC/PAL solution. You might check at their Google website.

    I cannot locate anything for TV or NTSC/PAL at the Google site... you might contact Prof Braino for a quick reply.
