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.
The manual was properly scanned and perfectly readable. The only small problem is that I couldn't use my dear Ctrl + F to find a word I needed.

Door reversal
Before carrying out the operations described below, pull out the mains plug from the wall socket. To carry out this reversal go through the following steps: 1. Gently lay the appliance on its back with the top held away from the floor by 5-8 cm (2-3 inches) of packing. 2. Remove the bottom door hinge (5). 3. Remove the door (4) by opening it and pulling it gently downwards to remove it from the top hinge pin (2). 4. Unscrew the top hinge pin (2) from the top hinge (1) and replace it in the opposite hole on the left hand side. 5. Unscrew the foot at the base (6) of the appliance and refit it on the opposite side. 6. Refit the door and the bottom hinge to the left hand side. When positioning the bottom hinge blade on the reverse side, the securing screws will require a degree of force when fitting. It is therefore advisable to lubricate the screw tips before starting this operation. Important After completion of the door reversal operation, verify that the door gasket is sealing onto the cabinet. If the ambient temperature is cold (i.e. in Winter), the gasket may not fit perfectly to the cabinet. In that case, wait for the natural fitting of the gasket or accelerate this process by heating up the part involved with a normal hairdryer on a low setting.
