The Paradise made 3 similar VGA boards: VGA plus, VGA plus 16, VGA 1024.
The VGA plus is an 8 bit version of the VGA plus 16. Its maximum
resolution is 800x600x16. The VGA 1024 has 2 possible configurations:
256K DRAM or 512 DRAM. The 256K Dram can do 1024x768x16 colors, the
512 DRAM version can go up to 1024x768x256 colors. I do not know
anything about the internal chip sets, but I could open up a few
of the computers and read the chip numbers if anyone is truely
interested.
