The circuit was designed to implement the concept of Sam Gordon in making a digital clock with visible components from the viewer of the clock. Sam Clock – a digital clock equipment that is fully parametric or constantly varying with its parameters of function and construction, which has been operational for many years without problems on a 24 hour basis. 74HC – a quad 2-input NAND gate with standard output capability, and is high speed Si-gate CMOS device that is pin compatible with low power Schottky TTL and specified in compliance with JEDEC standard no. 7A. 74LS – a monolithic decade and binary counter that contains four master-slave flip flops and additional gating to provide a divide-by-two counter and a 3-stage binary counter with typical power dissipation of 45 mW and count frequency of 42 MHz. 4060 – a 14-bit ripple counter with internal oscillator that has glitches which may occur in any logic gate systems connected to its outputs due to the slight delay before the later coun...
