It's been a while but happy to present this #fixitfriday The Turbo Duo is a Turbografx/Turbografx CD combination system that was released by NEC in 1992. Although several versions of this console were made, the best version is the Duo-RX which was only released in Japan. For this #FixitFriday we will go through a complete restoration of this rare console.
All Turbo Duos suffer from low-quality capacitors which can prevent the console from working correctly. Even worse, they leak electrolytic fluid onto the board which is corrosive and can destroy traces.
Fortunately there was no permanent damage on this system and all the capacitors were replaced with modern ones. After the system was repaired, we installed a region free mod kit so that American and Japanese HuCard games were playable. A small switch inside of the cartridge slot allows you to toggle between American and Japanese games. The system is now fully restored and has even more functionality than ever before.
