@vampiress If it’s any consolation, the original Commodore joystick was the same as an Atari joystick, just injection moulded in a different color.
The pinouts on the DB-9 were the same.
There weren’t many joystick OEMs at the time.
If you pull it apart you’ll see a board with switches made out of steel wafers pressed into a dome shape which completes a circuit when flattened. The wafers eventually crack. These joysticks are definitely life-limited.
