On a lark, I took a spare CPU board that I got off of eBay, popped one of the RAM chips off the CPU board in the machine, put it in the empty socket on the spare board, wired the spare board in the machine, and flipped on the power:
OK, so the machine seems to boot up now, but it is still not without problems. There are three things I need to address:
- The spare CPU board does not have the 3 AA battery clips, it has been modified. I suspect this could be why I get the message “Adjustment failure, restore factory settings by opening front door and turning game off and on”.
- The one player start button does not seem to work.
- The monitor has some interference at the top and on the right side.
But all in all, I am happy that for the first time in about 10 years, Robotron sounds can be heard throughout the household.
