Motorola made a variety of 030 CPU without an MMU built in. Without the MMU the Mac can't support virtual memory. The card won't activate without the Allegro extention. (Just like the DayStar 030 cards don't work without their control panel.) I don't know why Sonnet used the 030 without the MMU. ===== http://www.junkscience.com "All the Junk that's fit to Debunk!" __________________________________________________ Do You Yahoo!?
