I've lost interst in Diamond hardware for another reason:
The STB Evolution VGA card

This card does everything the Diamond cards do, 4/8/15/16/24 bit color,
clock synthesizer (and a BETTER one than Diamond's!!!), on board mouse
hardware eith separate color space in the DAC, and the ability to go into
a linear memory scheme, and as if all that weren't enough, it has the
ability to use all the fancy 4 plane hardware in 8 plane mode!

This puppy vidspeeds identical to a Diamond and has twice the winmarks.

Documentation on the board is available from Cirrus Logic, you need their
CL-GD5422 data sheet. This is a true single chip VGA, the RAMDAC and clock
synth are all on board so with this data sheet you've got complete dox on the
STB card.

I'm busily hacking a driver for it.

Best of all the STB card costs close to 50% less than the Diamond cards.

Bye bye Diamond!
