Thanks for the advice. I unlugged the batteries, played with the
switches and rolled a ball through the gumball machine as everyone
suggested. And I found another fuse that had blown (F106 wiich is a
GI so I doubt related). And now...everything appears to be working
fine again, no errors on start up! I have no idea what the cause was,
but since it's working I'll just be happy. Thanks again guys
