Solder this tiny board to the contacts of the joystick ports on your Commodore (supports the C64, C128, and Amigas; generally anything Commodore) and it'll prevent static damage to ICs on the mainboard through the joystick port by wicking away the current to TVS (transient voltage suppressor) diodes because they present an easier path to follow. Protects the CIA 6526A and 6581 chips in particular because there are relatively short routes from the jacks to those ICs.

This is a simple PCB that takes a SOT-23-6 TVS diode package to provide ESD protection on your Commodore 64 or Amiga with Atari style DB9 joystick ports. Install by soldering over the existing DB9 connector footprint on the back of your computer mainboard.

0.6mm thick PCB's with nice beefy traces. Available as a pair of bare PCB's or assembled with LiteON L13ESDL5V0C6-4 TVS diodes. If choosing your own TVS diodes, look for ones with a 5V standoff voltage (since the joystick ports signal levels are 5V). Many suitable parts may start or have SRV05-4 in their part number.

A standard USB mouse can be transformed into a 1351 for the C64 or a mouse for Amiga and Atari computer; a regular USB gamepad can be used as a joystick for your favorite games. The adapter can learn which buttons to use from the gamepad through its programming mode, allowing any USB device to be used as a joystick.

When in joystick mode, even a mouse can be used for games like Zak McKracken or Maniac Mansion that utilize a pointer. This way, even if the game doesn't natively support a mouse, you can still use it. The reverse is also possible: games and programs like Eye of the Beholder or GEOS that expect a mouse can be used with a joystick in mouse mode.

The adapter has a USB-C connector, so if you want to use a mouse or joystick with a standard USB (USB-A) connection, you'll need a converter. If you already have a converter, any will work just fine. However, if you don't have one and would like to purchase it along with the adapter, you can select the appropriate option.

There are two options: the classic one that works only on Commodore 64 and is with the THT board or the new version that works also for Amiga and Atari in a new beautiful SMD package.
