Help With Homework Board Compatibility Issue

I have been working on trying to get the article written by Jon Williams in Nuts And Volts
to interface a ps2 controller for weeks ofcource to no avail.
I called parallax and
I try it without the 220's in the circuit and nothing happens!
But to get to the point, has anyone succesfully used a psx controller with a HomeWork Board? And if not... does anyone else know a way we could controll the robot
The robot is for Sience Olympiad's Robobilliards competion.
ps: I have used 2 different SONY DualSHOCK controllers
pss: The needed amount of buttoons are 4 drive buttons 6 arm buttons

The Homework board has 220 ohm resistors in each of the outputs and may be causing the setup to malfunction

That article is popular today ... I spoke with a customer by phone who was also having trouble with that project. He contacted me later to tell me that he found a broken wire. I feel pretty confident in the circuit and code -- double-check your connections. And the 220-ohm resistors on the BOE are not the problem, I am quite certain of that.

Why are you using microcontrollers for the event?
The inversion transistor was producin a bad wave!
I got a ttl hex inverter and it worked perfectly
the microcontroller allows us to preprogram arm positions.
