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

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

Only 5 screws and remove 3 ribbons you will get the main PC Engine Board

Because of its age the Caps are brocken and need a replacement.

After some exchange in the power area it works again

look how bad it looks because of leaking caps

how ugly it looks. Some alkohol for cleaning

exchanging of most caps to kerkos

after recap

jailbarfix too with replacement of 2 kerkos into: 4,7uF 16V or 25V

you will find them on solderside from the PC Engine Super Grafx.

What can we do with this kind of PC-Engine

a) Speedup and change it to 60Hz

-Exchange Osscilator X201 to 21.47727Mhz
-cut Pcz80 Pin 15
-Solder wire from Pad pin 15 to Pin 22

b) RGB bypass for best picture

I took the RGB Signal from C154 to C156 after removing the Kerkos. The wires leads directly to the Hu6260 RGB-Out

using the rgbbypass PCB

yellow wire to desoldered PIN 44 from HU6260 (C-SYNC)

I am using an old „french“ pinput from the 90’th. So I have to reroute some cirquits

Desolder Din and cut GND on Partsside for make standard french Version of Din8 Cable working.

Cut 5 Din Via circuits and wire as shown here
red audio 2 (right), white Audio 6 left, grey 5V
yellow desoldered Pin 44 from Hudson 6260 CSYNC

c) Jailbarfix

exchange C137 and C133 to 4,7uf/16V

d) jap/eng switch

you need to switch 8 wires (15,16,17,19,20,21,22,23). I done it with two  analog switches  MC14551BCP

I used my IFU-30 Unit, so there was no need to remove the RF Unit. As I didn’t wanted some wires to the left or right side.

I put all needed connections to the rear side. Power, RGB-Out, Audio Out.

I opened the RF-box removed the orignal switch and replaced it with UWRC switch.

ground to one side and the other side of the switch to the uwrc board

thanks again to micro, for his great Idea how to make the UWRC plugable, by removing the filters.

green wire uwrc controll switch, red and black to the signal led combo I created at the upper side

blue „bigger“ wires to the 7805 replacement for swiching the pce off/on

a red 5mm led and a green 5mm led dremel work and to the ventilation grid

no more heat -> replacement of the 7805

Great feature, you can power off and on the PC-Engine via holding select and Run for around 1sec. Ideal for users of everdrives. Hope this feature will find his place in all new internal receivers from micro

Final Pic

thanks to the PCB of micro and some reposition of the led usb powersupply it works great.

I put it at the hole of the original wire and with some hotglue it works

I used Pin 44 of HU C6260 C-Sync for Sync. So you have to cut the Video Signal to the Din Connector (yellow wire).

Black wire is optional, for „more“ GND

For the Din Pinout I used the old French Layout born in the 90ths. With RGB added to the 3 new Pins of the Din 8.1. The rest of Pins are untouched (exeption C-Sync)

3 resistors 22 Ohm are used for make PCE-TV work to output around 0,7V. The PCB is the 1st Revision of micro. Power is taken from a Elko nearby. (orange/black=GND, orange/red=5V)

Scart Pinout

Jailbars removement

After checking the picture there are jailbars

After replacement of two  capacitor the picture is great.

replace C909 and C923 with 4,7uf down under Hu C6260

You final reward will be 1000 Points

Wireless Rules

thanks micro
