It's been a while since I had computer architecture, so somebody correct
me if I f**k this up...

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)
