This is my idiot-proof schematic, for people that have no idea of electronics (like me) and want to build two pots with disable switch for port 2 potentiometers:
Just connect things together this way and you are good to go.
The components I used are the ones described by InactiveX in the first post of the thread.
The way I do the switch is by connecting the power lines of the pots of the same port together then onto the +5 lne, so all I have is to connect that line to a single switch. You don't need a DPDT switch. No power, no pot. Mouse works fine. I wouldn't like to power the mouse and the pots at the same time on the same pot, sounds prone to disaster.
As a side note, I wouldn't do almost ANYTHING that Alpha recommends.
I have to say I built this and really didn't think it was necessary to bother. I think different rate potentiometers might yield similar results.
There's basic ally NO software for this cartridge except this player and the original software which is poop. SID+FM sounds just DREAMY. I can lend my cartridge to anyone that wants to work on this.
