Pinout for old Siemens mobile phone

[^rooker]

I just found a small sheet of paper with the pinouts of an old Siemens mobile. Unfortunately I didn't write down the model type - but I'll hopefully add that one day.
Currently the information is in a rather useless state, but I *know* that I'll lose that small piece of paper - or can't find it when I need it, so I'll rather post this confusing mess here.
