Does such a card exist. I've looked on Lowendmac and it seems all the ones they show are unaccelerated ones.
I got a Micron Xceed Color Fusion and its quickdraw accelerated.
They didn't have that one listed. A good amount of resolutions avaliable to it too. Can't really find much info on it aside from that, though.
How much VRAM does it have?
The Weitek "Power 9000" video chip visible in the photos was a fairly popular "Windows Accelerator" chip for VESA VL local bus VGA cards. (Late 486 era.) This is actually a fairly interesting use for it since when used for PCs it was always pared with a simple VGA chip (since it lacked any VGA register compatibility). This lacks the VGA chip and just has a "generic" TI RAMDAC and... I'm guessing that big fat XILINX chip on the back does most of the work adapting it to the Mac's PDS slot.
Yes, the XILINX chip does all of the translation between the video and the PDS slot.
I also own one of the better QuickDraw accelerated LC PDS graphics cards, a MicroConversions 1724PD, which has some neat features such as hardware panning and zoom, a virtual desktop feature, and resolution switching on-the-fly.
it only works with a LC III PDS slot though, unfortunately.
