Crystal oscillator uses only onesection of SN7408 TTL quad AND gate. Use series-resonant crystal having 30-pF series capacitance. Adjust 1K pot for reliable start-up and symmetrical square-wave output. Diodes are 1N34A or 1N914. Gimmick is 1 or 2 turns of insulated wire wrapped around output lead.-Clyde E. Wade, Jr., An Even Simpler Clock Oscillator, 73 Magazine, Nov./Dec. 1975, p 164.
