PCEngine GT Replacement Controller Board

[tawy]

Hello,

A couple month ago, I was looking for a replacement controller board for my freshly acquired PCEGT.
Without any news from Turbokon who had the original idea, I decided to make one by myself and here it is !



The D0~3 lines are diode protected with 4x 1N4148WT/SOD523, a external controller mod is theoretically possible from the pads on the back of the board (not tested).
I tried to make it looks like the original board plus some cool pictures 

There are some issues :
The comlink connector is not working.
LCD shutoff is disabled > pin 8 grounded.
The jack connector is a little bit too thick, you have to file your PCEGT or to swap the one from your damaged board to this one.



25?

Thank you

6 boards sent until now and everybody seems to use thoses flawlessly.
On the Turbo Express the boards seems to fit without the need to file the hole (maybe there is another revision of the pcegt mold with a different design).

I bought one of these from tawy, and it seems to fit exactly as he said. (Mine isn’t completely functional, so I can’t test to see how it works.) I have a Turbo Express (not a PCE GT) and the COM port is a little high on it, too. Other than that, it’s a a direct replacement and a spectacular design. For the price and ease of use, I can’t complain. Just wanted to give feedback for anyone else looking for this.
