Fans and users of the classic Commodore 64 computers will find this project by Peter Edwards of great interest. Peter has created an Arduino-powered device that can emulate the tape deck for a Commodore 64, which will increase the reliability of playing tape-based software and reduce wear on original tapes.
The "Tapuino" converts the MP3 files of orginal tape recordings back into signals which are fed through an interface cable from an original datasette unit. With some work Peter has added compatibilty for "fast load" software and also created a neat user interface with an LCD so the unit can be reduced in size and portable. It's an amazing hack and a great way to keep the old 8-bit games alive
