A blast from the past...

I have a Z152 that I bought and assembled about 5 years ago.
I'd like to bump up the 4.77 MHz clock speed to something like 7-8 MHz.
This should bring me up to about 1986 technology at least.  I'm soliciting
anyone out there who might have some good ideas about how to do this to Email
me their thoughts.  At the time I bought the machine there were some kits
available to do this, but they were a bit expensive.  Besides I really want to
do this myself.  I'm thinking of a daughter board to replace the clock
generator chip.  I have an 8 MHz V20, but need to know what other chips might
have to be replaced.  I'm still broke, so I am willing to sacrifice speed to
minimize the number of chips that need to be changed.  I would really like
to have software control over the speed setting as well.  Don't worry about
being to specific, that is really what I need.

   Thanks in advance,
   CEJ
