[comp.sys.mac.hardware] 8x24 display card -- color hires?

wm@ogicse.ogc.edu (Wm Leler) (06/13/90)

Is it possible to use the new Apple 8x24 (GC or vanilla) display card
with ~1000 line color monitors?  I've read every piece of documentation
I can find on it, and haven't a clue.  In 1152 x 870, 8 bit mode,
Apple only mentions their two page monochrome monitor.  Is there any
reason I can't purchase someone else's color monitor and use this as a
1152 x 870, 8 bit color display, or is it only possible to do color in
640 x 480 mode (24 bit color will only work in 640 x 480, but I'd be
happy with 256 colors in 1152 x 870 mode).

The only reason I could think of why it wouldn't work is if Apple
used a high speed DAC in only one of the 3 channels.

If possible, does anyone know of a color monitor that can handle
this scan rate?  Even better, is there a multiscan monitor that
can do both 1152 x 870 AND 640 x 480?  (If someone would come out
with a monitor that can handle scan rates all the way from NTSC --
15kHz horiz / 60Hz vert -- up to 70kHz / 75Hz, now *that* would be
impressive!)

Thanks a million colors!

Yes, SuperMac does, it's called the 'platinum two-page'. SuperMac can be
reached at (408)245-2202.

Disclaimer: I work for SuperMac, I'm probably biased etc etc
