The I-Pac2 I have has 2 PS/2 ports. Once I knew that it worked on another computer, I went back to the Mame computer and turned it on. Once everything loaded up, I plugged the I-Pac into the keyboard port of the computer. Everything froze, so I shut it down. In the past (when everything was working), I had the machine rigged so that I just had to hit the Power button on the keyboard to start up the computer...then it went right into the front end. After everything froze and I shut her down, the power button suddenly worked on the keyboard again, and everything works now. I went into Notepad and the keys were working again...go figure.
I don't even know what I did.
thanks for your help everyone!
