Hi Andy, if you breadboard the circuit, it would work.
You should load pin3 with a 10k resistor, because you can't leave floating pins with SPICE.
Then, as I told you, the VDC generator is not good for this circuit.
In real oscillator circuits the oscillation starts because you turn the power on. With SPICE you must emulate that event. The voltage of your generator must be 0 at t=0 and then rise to 5 V. You can do this with a VPULSE generator. Place it instead of the VDC generator.
Set DC=0, AC=0, V1=0, V2=5, TD=10m, TR=100n=TF, PW=8s,
PER=10s.
For the Transient Analysis Setup, set Final time=5s (you will see 4 periods, since fo=1,1 Hz). Dont'care of the first period that is different because of the initial transient.
