Recently I modded my good old friend… A Sega Master System 2 from my childhood, I’ve kept since 1993.

The mission were to make it possible to use composite/AV connectors on my TV, instead of the old RF signal port. This Sega console had to be hooked up between your analog TV antenna and your TV. With a switch box you could select to use the console connection, or the normal TV signal.

But since I hate connecting that thing, searching for the right channel, and lack of compatibility with modern TVs, I decided to mod my Sega with new video and audio output.

There were just one problem… Most of the guides tells you to hook your components up to a SONY chip. But my Sega had a much smaller Fujitsu MB 3514 chip instead. So I couldn’t solder my wires to the pins on my chip. So we had to wire it all on the backside, as you can see on the pictures.

It all went VERY WELL! Within a few hours my girlfriend and I modded the old beast, into a bit more modern console 🙂
