[sdiy] Siel opera6 schematics

[damsagain at free.fr]

Hi everybody,

I was searching a vintage Siel Opera 6 Analogic synthesizer when I found an ad
about it but the seller said to me that I would have to restore it.
Indeed he told me that integrated circuits missed on his Opera 6.
So I have a question :
- Does Siel Opera 6 schematics exist ?
I search on the web but I found nothing.

However I wonder :  Does it a good idea trying to fix that synthesizer while I
don't really know why IC have been removed ?

:-/
Thank you for your interest.
Best regards,
Damien
