"All components, pcb, keyboard, casing and internal hardware were supplied by Maplin in semi-kit form.

I personally constructed this in the late 70's , Maplin workshops set up all the boards that required it.

There is still a very small amount of work to do on this synth to complete it, the springline requires wiring in which is approx 4 wires, the joystick also requires final wiring up which is another small job. Anyone who remembers these synths will know about electronics and be able to follow the manual to complete it. The synth did play back in the 70's but I haven't used it since, I also don't have speakers etc now to listen to it on so I'm unable to run it now but there is no reason why it shouldn't work. You may find that some of the tantalum capacitors will require changing, it's usually the case with tants of this age, at least they would pop on my old Nascom which is from the late 70's. There is a very detailed manual which will come with the synth showing all the circuits and construction details, there is also a considerable number of pins for the patchboard. I have removed the back of the instrument whilst taking the photo's of the circuits for clarity, there is normally a back fitted."
