    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 PARCON Site

    The method used in your design need a lot of wiring and my need further buffering because of the large number of the I/O's. I think it is better to look for a design that uses minimum number of wires such as serial buses like I2C . Philips and Maxim has a wide range of I2C I/O expander you can make use of them .In the following link you can find a lot of I2C general purpose I/O expanders from NXP..
