There was a HP75 LEX file called ENTRYPNT that was used to decode hex addresses into symbolic labels (the entry points). It is mentioned in the note 2 at the end of this document:
ftp://www.hpmuseum.org/lif/swap/swap10/disasmdc.txt

Fortunately, I found this file in one of my archive LIF disc images!
Here is a dump of the beginning of the LEX:

The entry points are stored in a list of strings with the labels sorted from EAC7 A.ZERO, FBCD ABORT, ... to 0899 ZZZZZZ.

Attached is a LIF disc image with the LEX. It should not be too difficult for you to extract the table. Please share the result !

Note: I was unable to find the equivalent HP71 EQSORTED LEX mentioned in the same document, although there is a text file (also named EQSORTED) on the swap07 disc.
