The 14-stage CMOS counter is the 4020. But, if you want a timer,
use the 4060 instead. It is a 14 stage counter too, but includes a dual-
inverter oscillator on the chip. A couple of resistors and a capacitor
are all that you'd need with the IC for your 2-hour counter. One of my
favorite chips... :-)
