    A new 10-pin mini din was installed in place of the RF modulator. This is a Sega Saturn specific port so any Saturn cables can be used with it. It provides all the needed signals for composite, s-video, and RGB along with stereo audio. The channel select opening has a new replacement switch that acts to change regions between JPN (Left), and US (Right) HuCards.

    A new 10pin mini din installed to provide the neede video and audio output from the new RGB board. Here you can see how it installs using a new mount board in place of the RF modulator. Even though the jack is installed upside down here. The mainboard is also installed upside down in the console. As a result, the AV jack orients right side up so it works out well in this case.

    The RGB kit installed is called the Turbonanza and was designed and created by a well known modder by the name of Zaxour. The Turbonanza acts as a passthrough for the composite and s-video and audio. But provides new improved RGB signals to the output of the rear expansion port along with the ribbon cable you see providing the signals back to a new AV jack installed on the component side of the system.

    Here is the bottom overview of the TG16 mainboard. Similar to the Intellivision, the mainboard is actually installed upside down in the console. You can see where the new RGB bypass board has been installed using the pins from the expansion port on the rear of the console and then wired back to signal points.

    Pruchased used for about $20 at the local flea market back around 2000. Came with the controller you see in the picture but nothing else at that time.

    Here is another profile of the new mount board that was designed and installed into this console. It replaced an older design mount that also did the job, but was too small and fiddly to install. These newer mounts are easier to install with less guess work needed to line things up and actually cheaper to have made. I'm using a 9pin mini din for the RGB output. However, this older RGB board doesn't provide the proper level signals for Sega RGB use so it results in a darker than normal output. There is also no composite video present so c-sync is being created by stripping the levels for it needed for the standard sync signal and routed to the composite video pin.

    A new mount board was designed for use with the RGB upgrades. I initially planned to make the new mount board able to be used on both earlier 2609 model 1 consoles and the model 2. Differences in the internal layout and overall construction between the two models will require additional changes to use this on the model 1 and I will likely design a new option for the model 2. So the few of these I've had made will essentially be prototypes that I can use on model 2 units at least.
