Hi Niels, I also have a DANAHELM 3760 course computer. Did you already find the schematics? I know a guy who is able to repair this units. If you are still interested, please reply!

I also have a question referring this course computer: it can be connected to a control unit witch has a 7-pin-outlet on the backside. Can you tell me the order of coulors of the cables witch are connected to the unit?

Looking forward to your reply!

Best regards,

Memo
