"...they attached that stiff curly cord to the end of it, the cord weights more than the probe...." Read more

Great for troubleshooting vintage computers!

Great for troubleshooting vintage computers!
I got my first computer back in 1980 and build a homebrew logic probe that I have used until recently not that long after. I have started building homebrew and kit computers (around the 6502 and other vintage microprocessors) and in the process have found myself looking at logic probes as an alternative to dragging the oscilloscope around. This one works great and I'm happy I bought it. I thought the "tone" feature would drive me crazy and expected to either muffle or disconnect it, but actually it makes it easier to focus on getting the probe on the right pin instead of looking at the LEDs. Overall it makes basic troubleshooting (is there power where there should be, is the clock oscillating, are address or data pins stuck high or low, etc.) quick and easy. Would definitely recommend and now we'll see if this one lasts four decades like my original homebrew one did...

    I recently purchased this logic probe in order to fix some Neo geo and arcade boards I came across in a garage sale, toguether with my oscilloscope it has proven to be an invaluable addition to my toolkit. I was impressed by how intuitive it is to use, just hear the beeps when looking for a logic signal. The user manual is not very extensive but is clear and concise, but as a simple tool it is, it's easy even for someone with minimal technical expertise.

    Both plastic body and wiring are robust and should withstand daily use.

    The materials used in its construction are strong and no weird rubbers that may decompose, ensuring that this tool will be a reliable companion for years to come. If maintained properly, I am confident that it will last a lifetime.

    The tool performs exactly as advertised, delivering precise diagnostics that help in pinpointing issues with broken logic boards quickly and efficiently. It simplifies the troubleshooting process, saving valuable time and effort. Whether you're a professional technician or a hobbyist like myself I recommend you getting it.

    Finding and fixing an issue with the digital section of any electronic device is a challenge. This is a classic tool that can help you isolate a problem. I was happy to find this readily available on Amazon for a reasonable price. There are helpful videos on YouTube that show you how to use it and troubleshoot circuits. I recommend it for anyone working with add-ons to Arduino or Raspberry Pi projects.

    Logic probes are relatively simple and reliable bench tools that are indispensable for folks who repair old electronics. I have a 1980s vintage one that has been in use for a long time but it lacked one critical feature for me: audible tones. I am pleased to say, this "impulse item" on a recent order quickly became "why didn't I order it sooner?". The probe point is perfectly sharp and does not slip off of IC legs or pads easily-unlike my old probe. It also came pre-insulated, so no need to cut a piece of heatshrink and fit it to the probe just to avoid accidental shorts. Solid value!
