I have found in the datasheet for the 74HC4060
''The oscillator may be replaced by an external clock signal at input RS. In this case keep the
other oscillator pins (RTC and CTC) floating.'' I did that but still the counter won't work don't know why. I used the 555 timer to generate the clock.
There is no need to use a resistor for each LED. Tie all the anodes together and use one resistor from anodes to Vcc. My National Semiconductor data book recommends that R1(resistor connected to pin11)10X greater than R2(resistor connected to pin10) with the 4060 RC oscillator
