So, am I getting this right? You can speed up the GS just by changing the
processor and installing a new oscillator? Okay, maybe the faster chip will
require more power, but can the rest of the GS handle the speed increase?
What is the practical limit to speeding up the GS? ZipGS is available only as
high as 10MHz, but I have heard of GS's speeded up to much higher speeds.
