I have this mouse for 30 years now and I'm trying to fix it as it stopped working 20+ years ago (some wires in the cable broken). I already fixed the cable but I'm pretty sure the internal connector has pinout messed up as well - it tries to work but it struggles.
I need high res photo of the connector inside the mouse (or even better exact pinout of the connector vs db9 plug). I found some here: http://www.tcocd.de/Pictures/Peripheral/Logitech/mcj13.shtml but it's not clear. Mine had 2 wires swapped (perhaps stupid teenager HanJammer messed it up when first trying to fix it when it broke) so I guess something else is screwed up as well.
Any help will be appreciated.
