TapeBuddy64 is a simple and inexpensive adapter that can interface a Commodore Datasette to your PC via USB in order to read from and write on tapes. It is an advanced version of the TapeDump64. The integrated USB to serial converter can also be used as a SerialUPDI programmer for the on-board ATtiny814 (or compatible) microcontroller, so that no additional hardware is required to flash the firmware. The TapeBuddy64 is controlled via a command line interface or a graphical front end written in Python.
