They show up on CAT 2 as "TOULMATH-0B" and "-0C" respectively and contains a number of M-coded math functions.

This is very likely the Toulouse Math ROM. I've been searching for the bits of this ROM for a long time, without success. Even Emmanuel Compes, great expert in french ROMs, didn't have it.
It seems the project has never been completed.

The Toul. Math ROM project was mainly driven by Bernard Jousse and Eric Aubourg, and has been discussed in several PPC-Toulouse and Micro-Revue journals.
Some of the latest status can be found in Micro-Revue n°6 and following.
And we can read in Micro-Revue 6 p.62 (translation of mine):
"In MC, Eric [Aubourg ?] is in touch with Steen Petersen (PPC-DK 3, PPC 9583) who transforms his HP 41 into a HP 15, but a better one".
Small HP-41 world.
