This board worked very well since the first prototype, so here you go. Be sure to read the tech and assembly notes carefully and enjoy!
Released files
Note that the released gerber files are password-protected. The original reason behind my projects was to allow anyone to make their own retrocomputing accessories cheaply. Instead of this, what I achieved was actually fuelling greedy people grabbing my work, making boards for a couple of bucks and the selling them at outrageous prices ($15 for a badly-soldered OpenC64Cart that costs $2 to make is just ridiculous).
I still believe in free software and open hardware, and that is why my projects will remain as such. I am no longer providing ready-to-use gerber files, but you can still generate them from the KiCad project or ask me for the password, if you think you don't fit the above statement.
If all you want is to get boards made, I would really appreciate if you did it as explained in the Support section in order to get them cheaply while supporting the project.
Note that you are NOT allowed to use these boards commercially, but I won't care if you sell them AT COST. Let me repeat that: AT COST.
