Is there a Treo600 Developer Reference Guide?

I've seen reference to this Developer's guide on the net in various places (see JPA posting in:

I know that there is the palmOne_SDK_5_0_Docs_Developer_Guide.pdf available here on this site, however, on inspection it does not seem to be as detailed as mentioned in the above post.

I've been looking for information on the Telephony library. The palmOne_API_Guide for the Telephony library seems to be a relisting of the header files.
Does anybody have a copy of the old Treo600 Developer Guide perhaps which they might like to share? It help out alot.
