My expensive lathe digital readout just failed, and Newall does not want to repair it! So, we reverse engineer it, and find out that the proprietary principle of operation is absolutely genius, involving ball bearings and magnetics, with a readout precision of better than 10 microns. And the fault is quite unexpected. Hint: not a capacitor.
Update: Master Ken decapped the ferro-electric memory chip and made a blog about it, showing pictures of the unusual chip and explaining how it works. See it here: http://www.righto.com/2024/09/ramtron-ferroelectric-fram-die.html
