I mean, Simon is a retro game, right?
My wife has been wanting an old (late 70's/early 80's) Simon game made by Milton Bradley, similar to the one pictured above. After some digging at Goodwill, I was able to find one that was in decent condition. The buttons felt a bit mushy, the ground wire on the 9 volt battery connector was broken off, the D battery terminals were corroded and the battery cover was broken, and I may or may not be missing one of the switch covers. As I do with the game controllers that I find at thrift stores or expos, I felt the need to take the Simon apart and clean up the case and the board.
I'm glad that I did decide to take it apart for cleaning. There was some sticky substance around the edge of the case. Soda was probably spilled on it a while ago. That's the perfect reason to scrub it down.
There are some plastic retaining clips that also act as springs for the large color buttons. Most of those clips were broken. There was also a spare light bulb for the game that was rolling around loose in the case.
Another shot of the Simon mainboard. It was easy to just dust it as none of the soda got on the board and the battery corrosion didn't affect the board as well.
I took it all apart, including prying out the speaker from the bottom of the case, sitting just under the mainboard. I then took it to the kitchen to scrub every piece of plastic from the case. I also ran the corroded terminals in an ultrasonic cleaner with baking soda and water for several cycles. After running the terminals through the ultrasonic cleaner, I used a grinding pen to remove all the stuck corrosion. I also took the time to solder the broken off ground wire to the 9 volt connector.
There was a design online that I found for the replacement clips/springs that were all broken. I printed out 4 of them using PLA Plus filament. I also printed out some replacement battery covers.
Here are the clips installed. Fits pretty nicely and it pretty sturdy.
Originally, the speaker was installed with the plastic in the mold melted around it. I had to remove it so I could properly clean the bottom case, so I did need to break the speaker out. To reinstall it, I used a few dabs of hot glue to keep it in place.
I don't recall if all the switch covers were on there when I bought it initially, but the longer one for the Skill Level switch wasn't there. Luckily, there was a print available online. I didn't have a matching blue-green filament like the original switch that's on the Game Mode switch, so I used a blue/green two toned silk filament to print the replacements. I made one for the Game Mode switch, but there's a bit of post processing that needs to be done. I just left it alone.
I installed a 9 volt and 2 D cell batteries and used the printed battery covers. I turned on the game and...nothing. I was expecting some sort of "attract mode" with lights and sound, but there was nothing. I pretty much realized that I had to press the Start button to start a game. It happily lights up one of the buttons. I played a full game of it (well, as much as I can remember from the sequences). Happy to say that it works like how it should.
A fun, little repair and clean up of a game my wife really wanted. She's really happy to have this working Simon game, same as the one her grandma had in her toy and game bin.
