I have indid tried that circuit in my work bench, just with different values, it does work better.
I was playing with this one as I was thinking about Bob Boyce's circuit.

Now one thing interesting when the SIM is running this,,, if you replace the power source resistor with a wire, the SIM will crash.... SIMs will crash on OU circuits... they can't calculate...
