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.

INSTALLATION INSTRUCTIONS CONNECTING TO THE ELECTRICITY SUPPLY
WARNING: THIS APPLIANCE MUST BE EARTHED. DO NOT EARTH THIS APPLIANCE TO THE GAS SUPPLY PIPING. This appliance must be connected to 230V-240V A.C. 50Hz supply. It is supplied with 2 metres of 5 amp 3 core cable incorporating a moulded 13 amp plug, fitted with a 3 amp fuse, which can be plugged directly into the nearest suitable socket. If this is not long enough, the supply cable can be replaced 2 totally by a longer cable at least 0.75mm nominal cross sectional area (24/0.2mm). Ensure the plug is accessible to the user. IF THE MOULDED PLUG IS CUT FROM THE CABLE FOR ANY REASON, IT MUST BE DESTROYED OR DISPOSED OF SAFELY, AS THE PROTRUDING WIRES WILL BE AN ELECTRIC SHOCK HAZARD. If any other type of plug is used it should incorporate a 3 amp fuse in either the plug or adapter or at the distribution board. If the cable has to be threaded through small apertures in cabinets etc., it may be disconnected from the appliance, then re-connected to as shown in Fig.2. DO NOT EXTEND THE CABLE USING PLASTIC OR CERAMIC CONNECTION TERMINAL BLOCKS AND/OR INSULATION TAPE. ALL EXTERNAL WIRING BETWEEN THE APPLIANCE AND THE ELECTRICAL SUPPLY SHALL COMPLY WITH I.E.E. WIRING REGULATIONS. If the wiring is extended or a completely new cable fitted a 3-pin 13 amp plug should be fitted. (See Fig. 2a). Connect the wires as follows: BROWN to the Live Terminal. BLUE to the Neutral Terminal. GREEN and YELLOW to the Earth Terminal. As the colours of the wires in the mains lead which you fit may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is GREEN and YELLOW must be connected to the terminal in the plug which is marked with the letter �E� or by the earth symbol or coloured GREEN or GREEN and YELLOW. The wire which is coloured BLUE must be connected to the terminal which is marked with the letter �N� or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter �L� or coloured RED. FIT A 3 AMP FUSE TO THE PLUG HOLDER. Ensure that the supply cable cannot get caught by the stability chain. Plug in the appliance.
