"Soon a day will come when a large number of these classic early digital instruments will be renovated and making music again - but sadly this is one of the many that need an expert touch to get them working. This looks complete, with the crucial pedalboard, which is a vital part of the instrument and without which it is just a source of keyboard spares and a characterful early 70s piece of design. With RMI's classic and distinctive fold-down leg design. Please check the photos for its cosmetic condition - pretty good apart from some oxidisation on some of the stand and clasp metalwork, and some discolouration underneath the card reader. No cards are included, but it does have its lid, and an unknown switch (see pics).
Even with its neat leg system, this is a seriously heavy and large instrument, so will need palletising (60GBP) if it can't be delivered by hand."
