Luigi Di Fraia is working on version 3 of his DC2N. The DC2N is a digital replacement for the C2N datassette. With the DC2N you can read cassettes and transfer the data to a memory-card. It is also possible to save data from a memory-card to a datassette. The DC2N is a stand alone system, what means you can do the transfers without a computer. The newest version has USB support and uses a graphical screen to show the signal that is recorded. You can watch various videos of the DC2N on youtube.
