Hi alikat,
I found that transferring data from the KN7 (or the PR804) into the 902 is not possible, even after changing the instrument ID in the file header.
I am not a computer expert, but after repeated unsuccessful attempts, I think that the 902 has a file structure which is incompatible with the Technics instruments produced after it. This means that if the data are at all transferable, the files would require serious computer-based alterations to make them accepted by the 902.
Please note that the above is just speculation on my part, so if anyone out there is in possession of actual facts relating to this matter, we would be most interested in hearing from you.

Regards,
George
