	Actually, only the early TWGS's came at 6.25 mhz, because AE
had problems getting chips in quantity.  I got my TWGS in the summer,
and it was running at 7mhz.

	As for other differences, they are both supposed to be
expandable, the Zip is supposed to be easier though.  The rumor was Ae
was going to come out with a 12 mhz upgrade, and I heard somewhere Zip
was supposed to have a 10 mhz upgrade as well.  I don't know if this
is true, but does AE have an exclusive contract with ASIC for their
chips?  I think someone posted somewhere that at 10 mhz you couldn't
tell the difference in speed between the Zip and the TWGS.

	The Zip GSX is cheaper, which is a big plus.  The only problem
with the Zip is that the cda isn't in the roms.  With the TWGS, as
soon as I turn on the computer I have the CDA allowing me to change
speeds, do self tests, etc.  I believe with the Zip you have to load
in the cda, and whether or not it stays in memory as long as the
computer is on, I'm not sure.
