Radius PrecisionColor 8-XJ

Physical Specs and Compatibility

The Radius PrecisionColor 8-XJ card is either a 7" or 12" NuBus card (there were two versions) compatible with 680x0- and PowerPC-based Macs running up to Mac OS 8.1. It may be compatible with higher versions of the Mac OS but no information for Mac OS 8.5-8.6 is available at this time, and it's doubtful that the card is compatible with Mac OS 9.

Acceleration/Resolution/Color Support

The card provides standard QuickDraw acceleration and supports the following resolutions in up to 8-bit color:

512 x 384
640 x 480 @ 66.7 Hz or 60 Hz
800 x 600 @ 75 Hz
832 x 624
1024 x 768 @ 60 Hz, 65 Hz, and 75 Hz
1152 x 870
1152 x 882

Other Notes

ROM v2.0 or higher is PPC-compatible; older versions may not be.
Probably the most versatile NuBus video card that is still relatively easy to find on eBay, where you can usually get one for under US$15. If you have a 20" or smaller monitor that you can't drive with anything else, this card will probably drive it.
This card supports NuBus block transfer, providing an added boost if used in a Quadra 840AV. This will probably also speed up the Apple 4•8, 8•24, or 8•24GC cards in the same computer.
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.
