017- Is it really necessary to increase board voltage
to do a TWGS/ZipGS speedup?
With the new 14 MHz parts, you should not need to mess with the voltage at
all. It _may_ be necessary to increase voltage at 15-16MHz and will likely be
necessary at higher frequencies (e.g. 20MHz).

018- If I do a TWGS/ZipGS speedup mod, what kind of
performance increase can I expect?
This is just to give you a rough estimate of how much faster you might be able
to achieve...
