Anyone know what this is?

via this auction

"Rarest synthesizer in the World, as far as I know. Possibly a prototype, that never went into production?
Analogue / Analog Synthesizer with Line Out Socket and Speaker. Power Supply and voice/patch sheet, included.
Size : 13cm x 21.5cm . Will work with any 4.5Volt or 6Volt power supply, with + centre pin setting.
(Florian Schneider, Ralf Hutter, Graham Massey, Vince Clark, Martin Gore, Jean Micheal Jarre or Aphex Twin, have not got a Mini Synth)
(Even George Lucas and, Star Wars sound engineer friend, Ben Burtt, have not got a Mini Synth)
Reason for selling: Mini Synth needs a proven synth-master, to wield this analogue monophonic powerhouse.
Please, study all 9 photographs of the actual incredible items for sale."

Update via the comments: "based on the 3 switch 'Mixer' and the mixer truth table hand written on the back of the device, it looks to be based around the TI SN76477/SN76488 sound chip"
