I'm finally got my Bally/Midway Blue Print working this weekend. The game plays great but I can't seem to change the dip switches. When I go into test mode, it shows that all the dip switches are in position 1 (off), despite that many are actually on. When I flip one of them on the MPU, it doesn't change anything on the screen, still showing off.
Seems a bit weird that both SW1 and SW2 sets of switches are reacting that way. Makes me think the issue is not with the switches but rather somewhere upstream or downstream.
Any ideas?
