One to rule them all. Flagship of the PC-Engine Fleet -The Supergrafx.
A customer asked me if I can put a SSDS3 inside a Super Grafx and I loved the idea

It holds enough space to put a complete SuperSDSystem3 inside.
Now its possible to have the complete PC Engine Software Library including all CDs in one unit and it looks like stock level.

Removing the original Extension Bus makes it easier to put all the wires to the SuperSDSystem 3.

A lot of wires needed

testing with original RGB Output from the SuperSDSystem3

Removing the original DIN A/V Connetor and replacing with a DIN 8.1 to make RGB
Output via the original A/V Port

a shieded cable to the A/V Port

and with the cover on the backside you see “nothing”.

We call it SuperSDSystem3 inside

As I have open the Super SD System 3 for the Audiofix. I change the Mini Din A/V Connector to my common 8 Pin DIN connector, because I have a lot of consolse fitted with this same connector.

I am not a friend of cables from different sides of a console. So i put both RGB and Power supply in the back and have a nice looking PC-Engine Combo

Pinout RGB

The Powersupply +9V at the red wires GND at the black wires

I used a big diode to avoid wrong input voltage

you can hear a lot of digital noise, when accession SD Card. This fix solve it and we have silence
With the help of a single 10uF 10V Elko its done. Minus at the yellow Cap, Plus to the via
