Getting the Zip GSX to run beyond 12 MHz is just a matter of replacing the
74F00 logic chip with a 74HC00 (highest priority), adding a voltage regular
and two resistors to get >5 volts and having a good combination of static
rams in tag and data.  I'm currently running my Zip GSX 64k at 15.5 MHz
without any kind of problem.  I use and consider the following programs as
a good test of reliability:  NoiseTracker (the most picky), ProTERM
v3.0/3.1, Task Force, AWGS, Finder and Platinum Paint.  Your accelerator is
not reliable unless all these programs run without even a glitch.

OOTW (full screen) is a real challenge at 15.5 MHz... ;)
