Radio shack Digital Probe Micronta 22 303 Vlog-11

Radio Shack Digital Probe Micronta 22 303.
This is the Radio Shack Micronta Digital Logic Probe 22-303. First advertised in the 1987 Radio Shack catalog, it was sold for $16.95. A logic probe is an inexpensive, handheld test tool used for analyzing and troubleshooting digital circuits. It indicates the state of a BOOLEAN digital circuit, which can be either zero or one. If the probe indicates a zero reading, the circuit is in the off or no voltage condition. If the probe indicates a one reading, the circuit is in the on or voltage condition. The probe is usually powered by the circuit being tested, which is why there are 36-inch red and black alligator clip leads attached to the rear of the probe. This probe is compatible with both TTL (transistor-transistor logic) and CMOS (complementary metal-oxide semiconductor) logic integrated circuit devices. The pulse-detecting electronics typically include a pulse-stretcher circuit, ensuring even very short pulses are visible on the LED. Now that we've covered the basics of this tool, let's move to School Tube and discuss how it is used. We'll review three basic gates and their truth tables, then use the voice chip to demonstrate how to use the probe. Please note, I haven't taught or used this technology since 2009, so my understanding might be a bit rusty. The logic probe was invented by Gary Gordon in 1968 while he was employed at Hewlett-Packard, or as we call it today HP. There you have it the Radio Shack Micronta Digital Logic Probe 22-303.

Yeah, I drew an exclusive or gate. It should have been an or gate. But, I didn't put the second line at the rear of the gate.
