I'd love to help but sadly can't. It occurs to me that lots of us 
probably have a few things to add to the list. Perhaps we should all 
post them in one go to maximise our chances?

For me, I would love to get hold of service docs for any of the Seiko 
DS-series additive synths:

DS101, DS202, DS250 keyboards
DS310 and DS320 add-on modules
SIB-1 MIDI interface box (would also like a physical example of this)

Service manuals DO exist in this case but are extremely rare - I saw one 
once in an eBay auction but it was part of a package that I missed out on.

Who's next? :-)
