Build an Amstrad Joystick Autofire

[@pcroom34]

Nice mod. Can you tell me exactly where the adjustable resistor goes. I have made a similar thing and my auto fire works but I can't figure out where to put the variable resistor, any help please.

I must point out that the board I bought was the one from ebay and my design is for Atari/Kempston pinout
