I have an early series PCB, D8356, and they are no batteries in the upper right sockets. Are these needed for normal gameplay? What polarity do the batteries go in?
Besides the batteries, Here are a few of my problems:
When I finally got my Defender to power up, it stayed on the Book keeping screen.
If it shows Coins 0000, then I can do the switch from 28 back to 1, sometimes have to do it twice, and it will go into the game over mode.
Sometimes it shows Coins ????, if it does that then I can't get into it.
While in game mode, I have no sound. When I first started playing with it booting up, I heard some start up sounds and beeps, but no that I have game play I have no sound. (EDIT: I did see another thread of someone replacing the 6808 chip and their sound started work, so I'll look into that, but any other ideas are welcome)
During the game being on about 5 minutes, the "All time high" list goes from scores to all "???", and my settings change. (number of men, difficulty, etc..)
