Hi There,
I havent tried to do anything at low-level, such as directly driving the chipset etc. (and that raises another issue about buying chips(sets) etc, when i can simply use a $5 2-4Mb vga card, and plug into a isa/pci slot on my pic board.

i have tried a few experiments with driving the vga connector directly from a pic (also via eprom) but is is far too time consuming to calculate each line, timing, position etc.

I think it would be far easier to let the vga card all the scanning/timing work, while i simply control the address,data,control pins on the isa/pci connector to make a vga card start displaying my data or menus.

Marty ;-)
