I have a working 74HC14 oscillator:
"One gate of a 74HC14. 470ohm resistor from gate output to the parallel
of 1Mohm//XTAL. 10pF and 33pF (from the junkbox) capacitors to ground on
each side of the XTAL."


I have successfully made a circuit using a single gate of the 74HC86 similar
to you describe. I used 1K from the gate output to the 10MHz crystal. 12p
capacitor on either side of the crystal to ground. It works very nicely! See
the circuit diagram he
