This board is specifically designed for the TED series of Commodore computers (c16, c116 and Plus/4) and it is based on the work of Levente Hársfalvi (https://www.commodore.ca/manuals/funet/cbm/documents/projects/interfaces/plus4joy/plus4joy.html) and, of course, on the original Unijoysticle 2 by Retro.Moe (https://gitlab.com/ricardoquesada/unijoysticle2)

It uses the same firmware as the C64 version and works exactly the same, except for two particularities:

• Joystick #1 and #2 are swapped (AFAIK, default joystick in c16 games is usually #1)
• The board can be self-powered or USB-powered, there is no barrel jack

Important

Board **must** be 1mm thick or the mini DIN connectors won't fit!
