Key printboard schematic for Clifton SLM-37 = Sheffield SLM-37

Hi !
Do anyone have a schematic or good picture of key printboard - Clifton SLM-37 = Sheffield SLM-37 ? Both have same internal configuration.
I received one broken, I would like to restore it but is difficult to imagine the originl wiring.
Thanks.
