Thanks Chris for the help
What you mean by paralleled?
So what does the pulse stretcher do again? explain more please
It just makes you visually so on the Logic Probes lights alternating?
Is using a Logic Probe better at testing logic levels for TTL and CMOS , VS an oscilloscope?
Because TTL and CMOS have different Logic LOW logic voltages
For me, when looking at TTL and CMOS logic LOW state voltages , I can't tell if the output is Open, DEAD or a low state on an oscilloscope, how can you tell the differences?
When a Logic Probe it will tell me if my output on a TTL and CMOS is a LOW STATE or a DEAD output or a OPEN high impedance
How can you tell on an oscilloscope?
Also why A logic probe is better at testing logic levels is because the logic probe has the perfect probe impedance for logic outputs VS an oscilloscope it as a 10meg ohm impedance which loads the logic output
A Logic Probe has the Pulse Stretcher circuit so you can use it with a Logic Pulsar for troubleshooting
Since an Oscilloscope doesn't have a pulse stretcher circuit you "can NOT" view the logic pulsars microsecond waveshape in real time for troubleshooting using an logic pulsar right?
Open collector outputs may be paralleled since there is no conflict with one out being LOW and other outputs being HIGH.

A logic probe does have a pulse stretcher. This is needed to make a pulse that would be far to short for a human to see long enough to do so.
