Wanted: Monroe 620 schematics - Kees Bouw - 03-21-2022 10:54 AM
Hi,
Does anyone have schematics for the Monroe 620 desktop calculator from the early seventies, or know where I may find these?
I am also interested in schematics for the Canon L121 which is an almost identical calculator.
Thank you very much!
Kees.

Wanna look here? For the Canola L121

Maybe he has the service manual (as he gives details from it)?
Would be interesting for me as welll as I also have a (working) Monroe 620.

Another site is Hilpert's in Canada:
madrona.ca/e/eec/calcs/Monroe610.html
same unit without the memory.
It has a schematic very similar to Andi's suggesttion, but arranged a bit differently.
