2, 4, 8, 32, 64, 128, 256, 512,
1024, 2048, 32768 Hz Oscillator

A low frequency xtal-controlled oscillator/divider using CMOS CD4060BE
and a salvaged 32,768 Hz "watch" crystal.
The low resonant frequency (32KHz) crystal, is physically very small! (2mm dia x 6mm long)
From researching:
A quartz crystal resonator, used as the timekeeping component in quartz watches and clocks,
is formed in the shape of a tuning fork.
Most quartz clock crystals vibrate at a frequency of 32,768 Hz.

Outputs from the 4060 will provide the following frequencies:
2, 4, 8, 32, 64, 128, 256, 512, 1024, 2048 Hz
Note: A CMOS 4060B (buffered) worked fine,
but the pin/function(?) equivalent 74HC4060
high speed TTL compatible chip was erratic in oscillation....unuseable!
