Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.
This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.

Important! Rough handling of the glass, especially at the edges of the front panel, may cause it to break. Removing the glass from the door 1.Detach the door and, with the handle downwards, place it on a soft, even surface. 2.Grasp the top glass panel underneath, and push it towards the door handle against the pressure spring, until it comes free. 3.Hold the panel gently underneath, and slide it out. Clean the glass panel Inserting the glass to the door 1.Insert the panel at an angle from above into the section of the door in which the handle is located. 2.Lower the panel. Place the glass against the pressure spring at the handle end, and in front of the retaining frame at the bottom of the door, then push it into the frame. The glass panel must be firmly attached!
