8. The Main Computer:

The Motorola's MC68328 is your main computer (CPU). Its heartbeat is controlled by a low frequency crystal at 32.768 KHz. There is a frequency multiplier by a factor of 506 raising the CPU's clock to 16.580608 MHz. There is no adjustment of crystal frequency. If your Pilot's internal clock is not accurate you have to change the unit. You can download product specs from Motorola's web site for better understanding how powerful is this chip.
