Cheap logic analyzer.

Just a very simple analyzer based on this circuit http://www.akikorhonen.org/uploaded/2008/05/logic_analyzer_schematic.png

Added a jumper to use it as an output port. The centronics, flat cable and some other things came from and old Epson printer. It's working relly nice using TFLA ('The Fabulous Logic Analyzer') as software backend, found at  http://tfla-01.berlios.de/

Look ma' cardboard!
