Congratulations for finding such a nice sample - mine looked like it came straight out of a landfill (it probably did, as the seller called himself "Recyclinghof" :-D).

Dunke, Thomas!
I have got my fair share of Recyclinghof's units as well, acquired to private sellers around Portugal.
Usually the sellers here try to beautify the goods in the best way they can, and when I finally meet them usually in a public place, I found out the hidden issues... but usually I buy the defective goods because the asking prices are on the low side.

The springs likely provide grounding between the circuit board and the metal face-plate on the keyboard. Early Voyagers used the same system.

I would like to thank you for the content and quality of you frequent photo essays. It never fails that I learn something new.

Hi, Mark,
Thanks for your kind words. You are very welcome.
I just fill the need to share what I can find for my collection.

Concerning the tiny springs:
You are right. And it makes all the sense.
Thank you!

I know about it because even the old Casios did the same.
What was I thinking this afternoon?
I know, red wine and electronics do not match well...
