            The Radio Shack "TV Colorburst Crystal" works at 3.579545 MHz.
I used one in my setup...it worked fine.  From the ads I have seen, both
chips are on sale...well worth the price!  They work very well.  It is
also fun to substitute different value crystals in place of the 3.12 MHz        
crystal.  A little hunting at local electronics shops should produce the
10 MHz.   Good luck!
