This is the newest version of El Dr. Guzman's open-source logic analyzer. Programmed with the latest firmware and tested before shipment. In the photos, one is a capture of some of the bus signals in an Apple II computer that I did, the other shows all 24 channels operating sampling the same signal. There has been a total revamp of the analysis software, including speed up of the rendering, autodetection of the analyzers, and the biggest change, all the Sigrok protocol decoders are supported! Software is available for Windows, Linux and Mac. Go to the GitHub page below for all the great details, click on the 'Releases' tag to download the appropriate software for your computer and click on the Wiki tab for all the instructions for using the device and software.
