PICXXYXX
Hello,
Interesting board! He use a PIC16C621. But, for poeple dont have the money or wish to do everything by themself, then, there is many projects avaible on the web with the shemas of the board that do the same thing ( with microchip 16f84 or motorola HC11, etc ). The price will be lesser ( about 15$ for the hole thing with connectors and microprocessor ).
Controling the paralel port is really easy but the serial port ( like this board ) is a bit harder and need a bit more time of coding.
So, you do a good job with Rodney motters, felecitations!
Salutations,
Fred
