OT: Interesting Documentation - Sanyo Calculator Message #1 Posted by Katie Wasserman on 27 Aug 2011, 8:35 p.m. On TAS I found a binder full of service information on a few old Sanyo ICC calculators and have scanned the documents for the ICC-0081 (this is the only one of the 4 calculators included in the binder that I have). Disassembly Parts Logic PCB (part 1) PCB (part 2) The level of detail seems extraordinary to me and I wonder if any other calculator manufacturer in the early 1970's produced this level of documentation. I have some service details on HP calculators and on Wang from this time but they don't some close to this. -Katie

Re: OT: Interesting Documentation - Sanyo Calculator Message #3 Posted by Katie Wasserman on 27 Aug 2011, 11:13 p.m., in response to message #2 by Nick R Unfortunately not, the service documents cover: ICC-0081, ICC-1121, ICC- 1141 and ICC-2161.

Hanson, Jr. on 28 Aug 2011, 3:01 a.m., in response to message #1 by Katie Wasserman Katie: 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.

Docs Message #5 Posted by Frank Boehm (Germany) on 29 Aug 2011, 8:54 a.m., in response to message #1 by Katie Wasserman 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.

Re: Docs Message #6 Posted by Katie Wasserman on 31 Aug 2011, 2:18 a.m., in response to message #5 by Frank Boehm (Germany) Frank, I'd love to have a copy of the Pocketronic service manual for my website. Do you have that scanned? Katie

Re: Docs Message #7 Posted by Didier Lachieze on 31 Aug 2011, 4:28 a.m., in response to message #5 by Frank Boehm (Germany) As this topic is about non-HP early calculators, I would be interested by manuals for the Sharp EL-8 or EL-811.
