Still looking for HP-41C/CV/CX HalfNut Schematics

[rocket.scientist]

Interesting. The appendix I mentioned ("Section VII Addendum to the HP41C/CV/CX service manual (00041-90472)" is marked with a reorder number of 00041-90542. The halfnut schematics seem almost surgically removed from the copies of 90472 I have found. I wonder if this omission was done by error in the 90472 document, but present in the 90542 version.

A mystery is afoot! I will see if I can find Ignazio. Thank you for this most excellent lead.
