- Apple Developer Support will soon be publishing a TechNote which is
- basically an updated version of my original posting. It will include
- information on the Q950, although there are really only a few differences:
-
- - 1024 x 768 monitor support
- - 75 Hz vert. scan, 60 kHz horiz. scan
- - sense line wiring: connect pin 4 to pin 7 (but not to gnd), leave
- pin 10 unconnected
-
- - 16 bpp support on all displays, including the 21" (providing you have
- enough VRAM - 2 MB is required for 16 bpp on 19" and 21" displays)
-
- - Q950 requires 80 ns VRAM - the earlier Quadras required 100 ns
-
- - it's faster, too, of course ;-)
