SuperMac Spectrum Power 1152

Physical Specs and Compatibility

The SuperMac Spectrum Power 1152 card is a 7" NuBus card compatible with 680x0- and PowerPC-based Macs running up to Mac OS 8.6. It may be compatible with higher versions of the Mac OS, but it's doubtful that the card is compatible with Mac OS 9.

This card can accept a daughtercard with twin 66MHz AT&T 3210 DSPs for Photoshop acceleration. The DSP drivers are incompatible with Mac OS 7.6 and higher.

Acceleration/Resolution/Color Support

The card provides standard QuickDraw acceleration and supports the following resolution/color combinations:

512 x 384 up to 24-bit
640 x 480 up to 24-bit
832 x 624 up to 24-bit
1024 x 768 (at 75 Hz) up to 24-bit

Other Notes

Does not seem to work with SuperVideo control panel software. If anyone has this card working with acceleration on, please let me know details.
SuperVideo 3.1 (still sold for $30 by RadiusVintage), which is required for full compatibility for some SuperMac cards (notably the Spectrum Power 1152), is compatible up to Mac OS 8.5.1. It is not compatible with Mac OS 8.6 and higher according to RadiusVintage.
