The processor would have to have several wait states for each Nu-Bus access since the bus is only clocked at 10MHz :-( So, some operations will certainly be much faster with the upgrade, don't expect everything to suddenly be twice as fast until Apple upgrade the Nu-Bux to operate at higher clock speeds (a la Steve Jobs' NeXT) >Thanks, > >Fred Hollander To quote Alf --- "No problem..." ----- Greg DeMichillie Apple Student Rep - UC Davis lgdemichillie@ucdavis.edu AppleLink: ST0178 Disclaimer: If you've seen one disclaimer, you've seen them all.
