  11. The MC68hc705k1 has five methods for setting up oscillation,
  12. but I can't find accuracies fro two of them.
  13.  
  14. Crystals, external clocks and ceramic resonators, I can find out the accuracy,
  15. but for the 2 pin and 3 pin RC oscillator, I can't find any 
  16. accuracy/stability specs. Obviously, an RC circuit won't be great, but
  17. if it can gaurantee less than 5% error (approx) then it might be useable
  18. for this project (with 25-50 copies, $$$ is important)
