> Make the following changes to the small circuit board.
> Keep the wiring short and as neat as possible. The set
> of 50 pins will be referred to as J1; the set of 40 pins will
> be referred to as J2. On the solder side of the circuit
> board, a square solder pad identifies pin 1 of each set of
> pins. All pins in the row with pin 1 are the odd numbered
> pins, all pins in the other row are even numbered pins. Refer
> to Appendix E for basic information concerning the pin
> numbering of IC's. Wires should be installed on the solder
> side of the circuit board.
> 1. Cut the trace that runs from J1 pin 45 to J2 pin 39.
> 2. Cut the trace that runs from U1 pin 7 to U1 pin 2.
> 3. Add a wire from U1 pin 1 to J1 pin 45.
> 4. Add a wire from U1 pin 3 to J2 pin 39.
> 5. Add a wire from U1 pin 2 to U1 pin 14.
