Does anyone have an electronic copy of the "OS/8 Software Support Manual"?

Hi, all, I have my sbc6120 here and wanted to do a little OS/8 programming, but I think I'm stumped for a particular bit of doco - according to the "OS/8 System Reference Manual" (DEC-8-OSRMA-A-D), the User Service Routine is documented in the "OS/8 Software Support Manual" (DEC-8-OSSMA-A-D). I've found many OS/8 docs on Highgate and Bitsavers (DEC-S8-OSSMB-A-D, the 1974 "OS/8 Handbook", memos, etc.), but not that exact one. The reason why it matters is that if you want to do file I/O, directory lookups, etc., you use the USR. For stuff that doesn't depend on OS/8 filesystem operations, there's plenty of info out there for FORTRAN, BASIC, FOCAL, assembler, etc. Imagine trying to program in UNIX without knowing how to setup and call stdio routines. That's kinda where I'm at. I've found one or two narrow examples where some code fragments call the USR for a particular function, but I really just need the Software Support Manual.
