Hi Marty,

Sorry, I wasn't clear enough in my post.

Using a PC/AT, are you able to write low-level code that will control the VGA card plugged into its own ISA bus? (Without using the VGA BIOS support, accessing the VGA registers directly).

Before you interface a VGA card to your PIC micro board, try first to write low-level VGA code on a PC running MS-DOS.
