Vimfuego is building a new device for the users of datassettes on Commodore computers. This device makes it possible to record the sound of a datassette to a PC. It is also possible to use the sound of the PC to load data to your Commodore computer. The device can be used on PET, VIC-20, C64/128, c16 and the Plus/4. You can read about the progress on the Lemon64 forum.
