Inductor on HP 25C board
I have acquired a 25C that I would like to repair if possible.
So far I have cleaned it and found an inductor falling appart. It is the component on the top right in the picture (above the right ram chip).
Does anybody know what it does and what value it should be? Mine is non-conductive Sad

Cheers,
Harald

Edit:
OK, I answered the question myself. It is the oscillator and according to Jacques Laport it should be 150µH.
