After trying to track down some technical info on the Opus 3 last week I finally bit the bullet and bought a copy of the Technical Service Manual online.
While I appreciate the service these people provide (it was certainly my only way out), it does annoy me that people profit from someone else's copyrighted material rather than sharing it freely.
In that spirit

Also, if anyone wants to post it on a website please do!!! Or can advise of a good website to send it to.
Thanks everyone.
