Protect your precious CIA chips with these ESD protectors.
Protectors use STMicroelectronics USBLC6-4 ESD suppressors / TVS diodes.
Use solder wick to remove some solder from the Joystick port connectors. Insert ESD protector between the pins and solder it in place. Use multimeter to check that there isn’t shorts between the pins.
Technically these will work in any machine that uses Atari style 9-pin controller but may not physically fit. For example these don’t fit in Amiga 500. Width/height of the protector is 20 mm.
