Here are my platform wiring diagrams. This is how I have done it, I am not going to explain 'how to' too much but if anyone is interested enough to copy this idea there should be enough information to do so with a bit of interpretation. For a complete reference on the parallel port interface and full build details goto Jims page. Jim has built a 2 DOF (soon to be a 3 DOF motion sim) I got all my info to build my motion sim from here and if I hadnt seen his page my sim would still be sitting on the floor, this concept is completely sound and works extremely well. Another motion platform can be seen here. Roland is an extremely clever man and his web site is full of information.
