Notes:
1. For optimum performance, order replacement diodes, transistors,
and circuit modules by Motorola part number only.
2. When ordering crystals, specify carrier frequency, crystal
frequency, crystal frequency, crystal type number, and Motorola
part number.
3. "Not Placed" means that components are for future use, and are
not placed on the circuit board at this time.
