Occassionally, all of a sudden it will jam in one direction or not respond to movement. I thought it might be due to not having a PS/2 keyboard plugged into my HotRodSE.
However, I figured it worked most of the time, so that cannot be the problem. I tried adjusting the keyboard delays and repeats as well, but nothing completely fixes the occasional problem.
I will attach a PS2 keyboard to the HotRod SE and try it again. Hopefully that will completely eliminate any issues.
