"This is a black 1984 Korg RK-100 MIDI controller. It has some scratches on the exterior but it works very well. It has octave switch and program change buttons, and a pitch bender. It doesn't have an AC adapter but it takes 9volt batteries. It's heavier than you'd expect, but in an awesome way.
Seriously, this instrument is a sight to behold and will certainly become the centerpiece of your own personal shrine to rock & roll history. Put it on display in a place of prominence, and during your next social gathering, your guests will find themselves congregating around your new keytar as though they have been ensnared in the gravitational pull of some immense sun. From near and far, strangers will come to bask in the perennial artistry of your keytar's exterior. While playing your keytar, you will be transformed. You will feel that you are a musical god perched high upon the summit of Mount Olympus, igniting the skies as your fingers cue an orgasm of synthesized arpeggios. In fact, let me be completely honest for a minute: This keytar is going to get you laid. Probably a dozen times, if not more. To not buy this keytar is to forgo an onslaught of lust-crazed women who will offer you sex and unflagging admiration in exchange for simply watching as you stumble through a rendition of Journey's "Separate Ways."
My friend, the next and most important chapter of your life starts with the purchase of this Korg RK-100 MIDI controller. " eBay Link

"The Korg RK100 remote MIDI keyboard (no velocity) is a 41-note controller for any MIDI synthesizer or module. There are program change buttons that can switch between 64 programs as well as program increment and decrement buttons. There are also 3 wheels to control pitch, modulation and volume. In some cases the mod-wheel can also modulate your synthesizer filter.

There are some scratches(tiny scratch) here and there .There are may be couple spots(tiny spot) that the paint is separated from the wood,which won't effect the sound or the playing.The keyboard has batteries in the battery compartment installed." eBay Link
"This is a used Korg RK 100 with a very nice anvil flight case. The keyboard works fine minus a couple of the buttons as shown in the photos. One key is slightly bent as well but it works just fine. There is a crack that crosses the handle but it does not compromise the feel of the keyboard at all. " eBay Link
"Up for sale is a non-working Korg RK-100 in solid mechanical shape. The unit does not turn on so there is an electrical issue somewhere. I received a different keyboard to gig with so I have not had the time to dig into this one. This would be a great keyboard for a repair or for parts. The keys are in great shape--all of them are very springy like they are supposed to be. The rotary knobs for pitch bend and mod have the appropriate spring return action. The battery compartment door is present, and the strap holders are solid. The body of this keyboard is solid wood. The paint has some chips and dings. " eBay Link

"Rare Vintage 1984 Korg RK-100 Shoulder Keyboard Keytar with M-Audio Midair wireless MIDI, Gibson Bag and a High Quality UXL Adjustable Leather Strap. The Keytar is in beautiful, almost flawless cosmetic condition, and all electronics and keys work perfectly.
This comes with the M-Audio Midair Wireless MIDI which allows you to control an external keyboard, sound module, computer based virtual synth. This makes for a cable-free, reliable, low-latency connection in a stage performance situation. I will also include the original standard MIDI cable with a locking mechanism that came with the Keytar. The Wireless midi base is auto-volt and can be plugged in 110V-240V sockets, you just need an adaptor to fit it in Aussie power points.
Winner will not be disappointed. " eBay Link

They called this a "remote keyboard" because it is not a synth and doesn't produce any sound by itself. It is actually a Midi input device, which means you use a standard Midi cable and hook it up to your favorite synthesizer, the unit can be used with batteries or an a/c adapter as well.
Included with sale- Remote Keyboard, 16ft Midi Cable, Original Manual & Korg Sticker, Original
Power cord & Gig Bag!
The negatives on this keytar are few and not really noticeable in person:
A very small scratch on back
A small nick on the corner
A couple of dings on the back of the handle
The gig bag is great but you need to keep the unit covered as the bag has a small area that is worn and can create some black dust after all it is 30 years old i have always kept it wraped while in the bag as you can see the condition" eBay Link
WORKS WONDERFUL, ROCKING VINTAGE CASE INCLUDED (ONE LATCH ON CASE IS BROKEN)
NO POWER CORD INCLUDED, SHOULDER STRAP SHOWN IS INCLUDED." eBay Link
