This is an easy-to-build two-bit audio digitizer for the Commodore 64 that has been published in issue 10/86 of the German "64er" magazine.
You can do a lot more with it than what I'm showing you in this video, like adding echo effects or speeding up playback.
You can find all required files for building and using this device on my Google drive:

The Gerber files are copyrighted by Martin W. and may only be used for non-commercial and non-profit use. You may sell your leftover boards for the proportional price that you have paid, but not for more.
Martin has typed in the original German text from the magazine, you can find it in the .doc Word document and use that for automated translation into your language.
Thanks to:
- Daniel D. and Kristian K. for designing this wonderful device and software in the 1980s
- Martin W. for making this replica and sending me a PCB
- The Forum64.de community for their continuous support whenever I am in need of help.
