I've seen people asking for these cables at various forums previously, but I've never actually seen anyone say that they've found what they were looking for haha :P So here I am, asking for the same cable! Anyone got any tips? Much appreciated!
Those are the connections for the digital board that was an option that allowed you to record to digital tape recorders. The boards are pretty rare, and expensive. Last time I was on TheSoniq's website, he had one for sale. Hopefully, the cables come with the board.
