Is the PC graphics board really 640x480 NON-INTERLACED? Does that mean it requires a monitor with 32KHz horizontal sweep? Those things are more expensive than the board itself!

I've seen it -- very nice. Actually, it requires two adjacent slots in the PC since the two boards are mounted together with a daughterboard in the middle. They are also OEMing a new monitor (Princton? sounds right) for the board. Looked expensive from the resolution and clairity.

If we're talking about a graphics display board, what about XY resolution, color pallette, perception of speed etc.? Keith Doyle {ucbvax,decvax}!trwrb!cadovax!keithd

The controller provides 640x480 resolution with 256 of 4096 colors. I saw an IBM demo of the new controller and monitor several weeks ago. The demo program dumped a series of very realistic looking pictures on the screen. It took the PC-XT about 7 seconds (?) to move the picture from the disk to the screen. Although the XT's hard disk is relatively slow, it was not apparent when the disk was being accessed (i.e. the screen fill never appeared to stop because of an empty disk buffer.)
