V3

This release is basically the same as V2, it just removes R1, which was not needed. The project was also ported to Kicad 5.

PCBs have been produced and successfully tested.

Support

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.

Note that you are allowed to sell these boards, I have nothing against that as long as you do so at an "ethical" price. This is why I am adding the following restriction (inspired by DiagROM): if this board is sold at more than 5€ + production and component costs, 25% MUST be donated to a LEGITIMATE charity of some kind, like curing cancer for example.

Version 2

Testing is in progress:

• On Amiga the board seems to work fine, provided that you replace R1 with a 0 ohm resistor.
• C64 TBD.

First Release

DO NOT USE

This release has a number of issues:

• PCB is too long, DB9 connectors protrude out of the board
• Button 2 is connected to pin 5 instead of pin 9
