Very helpful, thank you - I also bought a manual for a SS 1000DS on a CD via ebay.

You're welcome, thank you... Credit should really go to spikey1973 (author of post #18) and all of the collective contributors to the Service-Workshop-Manuals thread referenced.

Doesn't help you in the short term, but if you're interested in a hardcopy version, they do pop up on eBay periodically. I scored a clean one for my 2003 years ago for $50-ish bucks.
