Wanted: Monroe 620 schematics
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
https://www.oldcalculatormuseum.com/canonl121.html 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. |
