Sounds to me like perhaps the lack of 12V input to the controller
is hosing you over. You can solve this problem without having to get
a new controller, I'm sure. I'd tell you how right now, but I'm at college,
and my specs on the catridge port are at home (240 miles away). Perhaps
someone else out there on the net could inform us of which pin on the
controller to inject +12V into, so that the older controller will work
on the CoCo III....
