Yamaha PSR 550 synthesiser keyboard (needs work)

Please read ad carefully before submitting an offer! Yamaha PSR 550, in very good exterior condition. Works very well but has some major issues, so would be more a restoration project for someone. Several keys dead but looks to be simply dirty contacts. In addition, the floppy disk drive has long been dead, so recording of any kind is currently impossible. However I am including in the sale a GOTEK OLED emulator, which, once installed, will give this machine new life. I can even throw in a USB stick and a stand if required. When working, the Yamaha PSR 550 has over 700 voices, hundreds of rhythms and a 16-track sequencer. In its day it was a real powerhouse, and can be again. I do not have the original power adapter as it split (as apparently is a known issue with the large, transformer-like supplies) but the one I have runs it fine. The speaker grilles will also need a bit of a clean, but otherwise the outside is now next to pristine really. The synth has MIDI IN, OUT and THRU and a headphone jack as well as an input for a sustain pedal. Serious offers only please. Can be viewed on appointment and tested. Any questions you have, fire ahead. If anyone's confused, it's the keyboard on the top tier of the left hand stand (the one with the blue screen).
