This is probably the most simplistic accessory you could have for your Commodore. The Commodore 64 User Port Breakout Adapter.

The C64 User Port Breakout Adapter allows you full access to the pins hidden inside your Commodore. With this card you can finally access all the pins from the User Port.

Common Uses

• ESP8266 WiFi Modem Connection
• Arduino Interfacing
• Controlling LEDs
• Controlling Relays
• Any project where you want to interface with the User Port on your Commodore!

What You Get

• You get the board of course with the User Port adapter pre-soldered.
• Your choice of Male or Female pin headers. (Soldering Required!!)
• A warm fuzzy feeling of buying my first project for Commodore!

Syzygy Systems

I started Syzygy Systems in 2019 to finally motivate myself to make projects for 8 Bit systems, mostly Commodore. This is the first product I am releasing. It is very simple, yet very handy to us C= hackers! With the sale of these I will be using the funds to re-invest into producing more products and better products for the Commodore.

Thanks everyone for stopping by!

Check below for the "Datasheet" more or less the manual. Please note that these are hand assembled by myself, so variations in dimensions and components will occur.
