Was there any service information on the Sanyo ICC-808D in the binder? I believe it came out a year later than the ICC-0081.

The combination of the service manual and the patent provided a rather thorough documentation for the TI-59 including circuit descriptions, schematics, parts list, troubleshooting procedures and listing of internal code. But of course, that was the late 1970's not the early 1970's.

I have several early 70s Canon service manuals (including Pocketronic). They come with complete schematics, timing diagrams, plus PCB positives(?) - ready for reproduction of your own PCBs (sheets printed in black, left blank on the other side). Since other manuals I have (Denon, Olympia, Diehl) show almost the same level of detail, it seems to have been common to have *useful* service manuals. Funny enough, they were numbered and company property :)
But, honestly, it was not needed for later calculators - reduced to only a couple of parts, they were repairable by simply replacing one of the five key components.
