The VGA card became a reality. Just cut out a portion of my FPGApple
and synchronized the clock with that on the Apple bus. I didn't even
bother to take any screenshots as they are identical to the old ones.
The logic inside the FPGA duplicates all the Apple's video circuits including
the soft switches for the video modes. Everything written to Apple's memory
is also written to the card memory and scanned at twice the standard rate.
Looks spectacular on an analog VGA monitor. Takes about 3% of the logic
inside the FPGA.
