Hi friends,
I was looking for a long time in internet for a large amount of controlled I/O through the parallel port (without micro controller support) but I couldn't find any. So me and some friends made a 2040 inputs and 2040 outputs controller. You can find below the schematics for both the main card and the I/O. Now we are developing the software to sense and control this monster.
We also established a web site and we have collected there all possible circuit controllers via the parallel port. For more information on this project and the others also you may click **broken link removed**
