And this is what I did, if it helps.
I cut and stripped the ribbon cable already connected to the controller board then connected alternating pins (e.g pins 1,3,5,7) to one peice of veroboard, and pins 2,4,6,8 e.t.c to another peice. I then soldered thicker mulicore wire to the two peices of veroboard as well. In other words I extended the ribbon cabler, without having to solder tons of wires together.
Here is a better (but large) pic:
Those 4 spare wires are or L1,L2, R2, & R2.
I heated up the joints where the ribbon cable connects to the controller board, and the metal wires came free. I then used those wires to solder to. So I didn't have to solder the minute traces on the controller board.
What I basically did, was solder wires to the pins on the controller board, and then those wires go to the tacts. But the first set of wires I soldered were too short, so insted of elongating all those wires, I soldered them to verobard, and then soldered new wires to veroboard. Extending them.
My controller was like that, except the ribbon cable at the bottom was white (not green) and was actually made of wires, not this new plastic stuff. I split the ribbon cable, soldered the wires to veroboard, and then soldered other wires to the veroboard. In other words extending that ribbon cable.
) and I didn't sand enough. I don't know whether I can be bothered to re-paint it though...
