   If you can hack in another divide-by-2 stage, Mouser and Digi-Key both   
   carry 17.734475 MHz crystals, which would give you 8.8672375 MHz.   
      
   If this crystal's only job is to provide a digital logic clock, Mouser   
   and Digi-Key also sell programmable crystal oscillators for around $7   
   to $10.  You tell them what frequency you want and they program it for   
   you before shipping.  They come in little cans about the size of an   
   8-pin or 16-pin DIP IC; you supply power (usually 3.3 V or 5 V) and   
   ground and square waves come out.
