Hi,

Sorry for writing in english. But for swedish I would have to ask my neighbour to write the message...

I have a Stern 520-5197-00 Display here.

I can't test it, because the control is too complicated (lots of D-Flip-Flops).
But it looks very good, might even be unusdes so far.

I received it from a friend engineer, who once received it from an service technician, when he retired and closed his business.
My friend gave it to me, when he tidies up his makerspace. Now I have to tidy up....

If You arre interested in it, please send me a message.
You can even send me a message at: ing.michael.knecht@gmail.com.

If you have an Arduino sketch at hand that allows to test the Display, I could even test it.

Regards

Michael
