In C you can use the functions outport and inport, and the paralell port has TTL levels (5 V.).

Its Easy to do in pascal as well as C++ using the PORT[address] command. Ive used It before to control external devices. A normal parralell pot has 8 outputs D0 - 7 and a few lines that you can use as inputs (not sure which ones though?) The port (...) (25 years ago, 13-Sep-99, to lugnet.robotics.handyboard)

Isn't your parallel port itself what you want? I always understood that it could be reached (coded) quite easily? That should give you 7 channels! ----- Original Message ----- From: Peter <eacmen@att.net> To: Handy Board Mailing List (...) (25 years ago, 13-Sep-99, to lugnet.robotics.handyboard)

I disassembled quite some (lego) models, I also use differential steering. I position the wheels like most models on a square (so width and length of wheel base is equal). Funny thing about a square is that a circle can be drawn from the middle (...) (25 years ago, 13-Sep-99, to lugnet.robotics.handyboard)
