* '''Doubler software''' (Side A) executes an endless loop that forwards changes on Port F0E0h.Bit5 to PPI.PortC.Bit5 (and also to the Screen Border color). The software doesn't attempt to decode data blocks, it just forwards the data, and thus also works with any kind of non-standard data blocks. Similar results can be gained using a normal Dual HiFi Tape Deck - the advantage of the Draysoft method is that it outputs 'harder' digital transitions, however, it does add some timing inaccuracies, so the copy isn't exactly the same quality as the original.

* '''Speedcop software''' (Side B) is a baudrate conversion tool, allowing to select 1000, 2000, or 3000 bps (it. It's also allowing to remove SAVE"FILE",P protections. Speedcop is using only the internal recorder, ie. this program is not using the external hardware at all).
