Vintage Synth Repair

Greetings!

This is my first post to this fine list - I look forward to some interesting communications...

I have quite a collection of unusual vintage keyboards, some of which may be seen here:

I live in Tokyo, Japan, and while I do know some good repair people here, it is always a challenge to keep everything well maintained. Right now I have three instruments which have been sitting in said repair people's workshops for quite a long time, with not a lot of progress happening - which is one reason why I have joined this group.

So may I start by listing these three keyboards and asking if any members of this group own or have owned any of them, or may be able to help in any way with locating schematics, parts, etc. I won't go into any further details just yet. They are:

RMI KCII

360 SYSTEMS DIGITAL KEYBOARD

ACETONE CANARY

Many thanks!
