KORG LAMBDA ES-50 48-Key Polyphonic Analog Synthesizer SN 230602
Note: links to listings are affiliate links for which the site may be compensated.
via this eBay listing
"For the uninitiated, the Lambda is a fully polyphonic keyboard, brass and string synthesizer with two sections: Percussive (Pianos, Harmonics and Clav) and Ensemble (Brass, Organ Chorus and Strings). The sounds from these sections can be used in any combination and output together in mono or stereo.
The chorus phase effect is rich and sounds great when using the Lambda in stereo. The effect can be set to either or both the Percussive and Ensemble sections and its speed can be controlled with the joy stick. A pair of tuning controls allow you establish the range of the chorus phase, from minimal to lush to seasick.
Everything on the Lambda works as it should and sounds excellent. All the jacks work as well. The expression jack uses a control voltage pedal, not a standard expression pedal. I’ve used an Expressive Touché controller with this (set for 0–5 volts as required for the Lambda), and the keyboard responds with volume changes accordingly.
The sliders work fine, with no noise or stiffness. All the controls turn and function as they should."

360 Systems Digital Keyboard Mk II (MIDI)
Note: links to listings are affiliate links for which the site may be compensated.
via this Vemia listing
Click the auction link on top when you get there for additional listings.

"360 SYSTEMS DIGITAL KEYBOARD Incredibly rare early 8-bit sample-based keyboard (1982-1984, only 200 made). This is the Mark 2 type, with MIDI. Excellent condition apart from light scratches on the wood panels. Comes with printed manuals (1st and 2nd editions), parts catalogue, service history (maintenance done since the current owner bought it in 2005 - and since then only played it in his home studio).
12 of the 16 voice sockets contain voice chips as follows: 1 Flute / 2 Gut String Guitar / 3 Bass Guitar / 4 Slap bass / 5 Electric Guitar / 6 Electric Piano / 7 Clavinet / 8 Saxophone / 9 French Horn / 10 Trombone / 11 Dark Trumpet / 12 Bright Trumpet.
All functions are working fine except for one problem: This is an 8-voice keyboard, but if you play more than 6 notes at once, the 7th note produces a distorted sound. It seems that the 7th out of the 8 voices is faulty (doubtless due to deterioration of a vital part - no physical damage has been done to this carefully used machine). If it can be fixed or muted, you will have an incredible instrument with rich, organic tones. In any event it is perfectly playable if you respect the current voice limitation.
LISTEN! You can hear the sound of this actual instrument (arpeggios played with all 12 voices from bottom to top of the keyboard) HERE: [embed above]
Quote from a well-known pro user: 'It sounds AMAZING, the only sampler with enough character to rival a Mellotron or Chamberlin. My favorite French horn patch of all time!'"
