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.

STABILITY BRACKET
To reduce the risk of the appliance tipping due to improper use or door loading, it must be securely installed using the stability bracket supplied. 1. Place the stability bracket on the floor as shown in figure 2. If there is no side wall, the dimension given as 0.5 cm will be the distance of the left / right side of the appliance to left / right of the stability bracket. If there is a side wall, the dimension given as 2.5 cm will be the distance of the left / right side of the stability bracket to the side wall. If your appliance is 50 cm wide, the distance between the back wall and the top edge plate should be zero. If your appliance is 60 cm wide, the distance between the back wall and top edge plate should be 2 cm. Mark the locations of the 2 holes of the stability bracket on the floor. Use a 7.5mm masonry drill bit to make the holes and insert the plastic anchor. Secure the bracket to the floor using the screws supplied. Slide the appliance into place (Figure 1).
