The CurveBug is a debugging / troubleshooting 2-terminal curve-tracer tool, developed by VintageTEK to benefit their non-profit operations. The function of the CurveBug is very similar to the well-known "octopus" tester - which is a highly simplified version of the Huntron Tracker. I did a video on the Octopus that has been viewed over 300,000 times:

The CurveBug has two curve-tracer "channels", allowing you to simultaneously probe two circuits (one suspect, one known good) to look for differences and faults. Information on the CurveBug, along with the manual and software download, can be found here:
vintagetek.org/curvebug
VintageTEK sells the device from their Ebay store. Since a new Ebay link is created each time they build a new batch of devices, there's no point in putting the Ebay link here. If you're interested in one of these devices, simply go to Ebay and search for CurveBug.
