Hello.
I bought an Amiga 1200 which has a problem (I think) with the right button of the Commodore Tank mouse (and any other serial port mouse with Amiga adapter).
When testing with AmigaTestKit-1.20, no right-click activity is detected with any mouse I try.
The same goes for plugging into the other joystick port.
From what I read on the internet, everything leads me to the PAULA 8364 chip.

My question is - what are the numbers on the legs of the chip that correspond to the left and right mouse buttons?
I can't navigate the scheme!
35 and 36 I think are for the first port and 38 and 39 for the second port?!

And what values ​​should they read when the buttons are pressed?

Thanks in advance to those who responded!

Do you have any (real) two button joystick for C64/Amiga? Second joystick fire button is connected to same pin (9) as right mouse button. Left mouse button (fire button 1) is pin 6.

Basically, when you press any joystick button corresponding pin is connected to GND.

If that schematics is correct, pin 36 is right mouse button / secondary fire button (I guess on port 1 is mouse port), pin 39 is same pin on joystick port 2.

Left mouse button / fire 1 button goes somewhere else to motherboard. I guess because that pin always has same function. While pin 36/39 doubles as X axis for paddles.
