I have managed to get the PIC board using the 16F627 to work. When the input goes high ouput 7 producess a number of pulses pending which input is used. This works successfully.

However, when I attach the fly lead to the clock on the 4026 it dies not count up when a button is pressed. I have added a pull down resistor and diode.

Furthur more. A poulse is seen to be recieved when a multi meter was placed on the pin. Very strange.

any suggestions
