I started playing with my Qbert again.. I rebuilt the sound board and upgraded the 2 caps on the main board. I also bought the battery mod kit from Arcadeshop, but I haven't done it yet. Someone else along the way had done some other battery mod and added a lithium battery to the board. I've attached a picture. My high scores are still not being saved all the time, so I want to do the AS mod with the NVRAM chips. I know I have to remove the diode at D2 and put a jumper in. When the other battery was installed, they moved the diode at D3 and took out the resistor at 340. Do I need to remove the lithium battery, reinstall the resistor 340 and reconnect diode D3 before installing the other chips?
Also, I was running through the sound test in the menu, and I have no sound on test #'s 16,29,30,31 and 32. I don't notice any sound missing during game play, but its probably been that way since I've owned this.
