  18. > Also, can you tell me why programs in rom run faster than programs in ram??
  19. > 
  20. Programs in ROM can run at the full speed of the processor (normally 2.8 Mhz).
  21. Programs in RAM lose some cpu cycles due to the memory refresh required and
  22. therefore run slower (about 2.5 Mhz).
