History repeating… as dont have all the parts to finish my almost finished 9090. Ive decided to put some attention to my dust gathering Juno-60. I bought it from a Gypsy on a local flea market long time ago in not so perfect shape. Until few days ago it was gathering dust in my basement. There were mising some slider knobs, button caps, few keys are burned with cigarette, few key contacts and pots are busted too… a list goes on. The metal part of casing is rusty, and wooden cheeks are damaged, so not much of its outer beauty left, but its soul is fine. As Im not a keyboard player but midiboxer, I couldnt accept gear I cannot control externally with MIDI, so my old plan was to MIDI-fy it and to give it a new body.
This is how it looked when I got it. On this picture it don`t look so bad. 
As it was in basement for a some time it gathers a dust even more than it was, so I thought only way out is blowing it with compressor.
I really expected better results, but it is covered in some mixture of dust, dirt and everything else… so blowing it didnt gave expected results. You can see main board in all its shine and glory. 
I was surprised that control surface boards looks much better. This picture I took after dusting.
As already mentioned this synth I bought from Gypsy, and Gypsies music has a lot of “bending”. This is the result of hard core usage. I conclude this Gypsy has very sweaty hands.
Before I dismantled it I tried it for a last time to make sure it still works.
Juno-60 has 3 big boards. 2 CS PCBs and one main board. Main board is widest of all and it will direct me the width of the synth. I`m planing to mount the boards on the separate shelves one of top of other to make this synth as compact as possible.
This is left control surface board. I decided it would be much cheaper to use roto pots instead of sliders. Sliders are also harder to get for me locally.
These old PCBs are really fragile. I didnt wanted to damage the traces trying to desolder the mechanical parts, so I cut the leads off. I left switches alone as they dont make any connection when depressed so I can just solder the wires in parallel to them.
This I/O board looks pretty dirty too, so I`ll probably make another one or mount the those jacks to back panel.
I don`t have any service manual nor schematic for Juno, so I needed to lable the connections so I can put it back again.
This keyboard is pretty nice. The keys are big and have nice feeling. I`m not planing to keep integrated keyboard. I will probably shorten it to just 3 octaves and use the rest of keys to replace those burned by cigarette. This keyboard will be connected to MIDIO128 and become nice master keyboard.
It is connected as 8x8 matrix. I suppose all keyboards are connected that way.
