Found this simple parallel port logic analyzer http://www.xs4all.nl/~jwasys/old/diy2.html But can get the recommended parallel port driver to work under windows 2000 :-( Anyone have a good windows 2000 port driver? Or A better homebrew or cheap kitset logic analyzer? _______________________________________ Feel the power of the dark side!
