This simple and tiny adapter relocate the keyboard connector on the C64 Ultimate in order to use the right side support for the keyboard.
Tested on a real C64 Ultimate by Eric Gustafson.
Just plug this adapter, then plug your keyboard connector (check out pin number!!!) and you are done.
Please check pictures from the gallery to correct position. Not all the C64 Keyboard connector are the same. Some of them has pin numbers printed on the plastic connector, others don’t. Also this hat is only valid for the C64 ultimate v1.2, not valid for V1.1.
