A list of possible ToDos:

As publications on this system are rare, we should try to add any WP:RS discussing this to the "Further reading" section.
Try to find links to PDFs of the Hohmuth (1987) and Milde (1988) key sources for improved reader convenience.
List of UC compressed Eterna/Amiga/Nova records.
Photo of a Ziphona HMK-PA2223 turntable with built-in UC expander (also photos of its PCB and the "UC" logo).
Photo of an Eterna/Amiga/Nova record's deadwax showing the "U"/"CU"/"DU" code as part of the runout code.
Block diagram and excerpts of the original circuit diagram.
More detailed functional description.
More detailed technical specs (also sorting out if the maximum compression is 4:3:4 or 5:3:5 - sources differ on this)
Frequency and spectral curves.
Links to digitized UC compressed records played back with and without UC expander.
