I finally got back on this project and I opened up my Neo Geo Two Slot and did a lot of cleaning. Wetvacced the cobwebs and loose dirt, found $3.65 in change, took the lock off the coin bucket door, Simple green for the caked-on dirt, and started disassembling the Control Panel to clean the plexi and CPO. Also, I removed the bezel for cleaning and polishing.
I still need to go back and sand and put another coat of red on it, but for now, I am working on getting it cleaned up!
I noticed that the Control panel, power supply, Neo Geo Board are all on a sliding piece of wood that wants to slide out the front. Also, the Control Panel seems to have originally been cut for a two player 6 button setup. Does that help anyone here to identify the cabinet's origin?
