hmmmm... on the blizzard PPC have you seen the size of the jumpers you have to move around to change the CPU voltage from 5volts to 3.3volts? magnifying glass, a solid board mount, and a steady hand.
i'm not even going to go into getting to the jumpers for the bus speed multiplier for the PPC - which if i remember rightly, are under the clock generators, or the oscilator selecter for the 68k chip, cos really with an 060, i'd like it to run off the same crystal as generates the PPC bus clock so it is as syncronous as possible. the fact it'd be 66Mhz would be only a side benifit :-D
then there is the daunting 200 odd pins of the 040 to desolder, and of the 060 to resolder.
its all too scary for me :-o
