I called WDC about 6 months ago and they sent me a packet of information 
detailing what I would have to do to upgrade a TWGS to 13mHz, including
names of distributors to call for parts and even the part numbers. I know
Bill Heineman has his TWGS running at 13mHz, but he made _all_ the mods
in the 'walk-thru' that WDC sent me, some of which can totally fry the board.
