Radius PrecisionColor 8-24X

Physical Specs and Compatibility

The Radius PrecisionColor 8-24X is a 12" NuBus card compatible with 680x0- and PowerPC-based Macs running up to Mac OS 8.1. One reader reports success with Mac OS 8.6 on a 7100/80av, although the QuickColor extensions don't work. Another reader reports tht it works on an 8100/110 under 8.6, although there is some "video garbage" during boot.

It may be compatible with higher versions of the Mac OS but no information for Mac OS 9.0-9.1 is available at this time, and it's doubtful that the card is compatible with Mac OS 9.

Acceleration/Resolution/Color Support

Two versions of the card were made: one has support for up to 8-bit color, the other has support for up to 24-bit color. Both versions provide standard QuickDraw acceleration and support the following resolutions:

512 x 384
640 x 480 @ 66.7 Hz
832 x 624
1024 x 768 @ 60 Hz or 75 Hz
1152 x 870

Other Notes

The 8-bit version is usually substantially cheaper than the 24-bit version, so if you only need this card for driving a second monitor for palettes or the like, don't pay the extra money for the 24-bit version.
QuickColor 3.3 (part of RadiusWare 3.3) works fine under any Mac OS up to and including Mac OS 9.1.
Dynamic Desktop crashes the Mac OS at startup when installed on Mac OS 8.6 or higher. SwitchRes (shareware) works to change resolutions instead.
