via the seller: "I built this synthesiser in the 80's and I have finally decided to sell it as I do not have time or space to use it any more.
It is still working but not fully. It has not been fully tested for some time.
Minor repairs are required and I suspect some internal wiring might need modifying to get it fully working.
The Hard Case is in excellent condition.
As you can see, the Patchboard comes with 12 original Patch Pins.

Specifications:

4 x VCO's (one in need of replacement Potentiometer)
5 x Mixers
2 x Filters
1 Envelope Control
2 x Transients

1 x Patchboard with 12 Patch Pins
1 x Joystick
Foot Pedal Controls but NO Foot Pedal.

An excellent project for an enthusiast or to break down for spares"
