Combined beakout and prototyping PCB for the Userport of the C64/C128
C64UserBreakout is an open-source printed circuit board by hackup, from the hackup/C64UserBreakout repository on GitHub. It is a 2-layer board of 58 × 85.5 mm with 491 parts on 21 nets, routed with 189 tracks and 2 vias.
Its parts include 5 connectors and 1 switch.
This is a combined prototyping and breakout PCB for the user port of the Commodore 64. It connects the user port to a standard 830 pin prototyping breadboard to assist with the development of modules or cartridges. In addition, it features a perfboard area that can be used for simple prototypes. USE AT YOUR OWN RISK!

It measures 58 × 85.5 mm and has 2 copper layers, 1.6 mm thick.
491 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the hackup/C64UserBreakout repository on GitHub, at the commit this page was made from: the board is C64UserBreakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask hackup before reusing the design.
