Simple 8CH Logic Analyzer

This is a simple logic analyzer i built using a Db25 connector, wire, 2 opto-couplers and a few test clips, the software called digitrace can be downloaded free with a schematic for the probe as well. http://jwasys.home.xs4all.nl/old/diy2.html the logic probe takes use of the now mostly unused parallel port. and is perfect for capturing basic logic on most circuits, i plan to build a better probe and post a video with my advanced probe.
