I'm mostly interested in the HP-15C assembler code but I'm fine with the HP-71B as well.
Could you provide a similar analysis of this function so we could compare both results?

In theory it could be disassembled, but without proper documentation it would be a gargantuan task to turn the resulting Saturn's assembler code into anything useful. Reverse-engineering the truly complex and highly-optimized algorithms of this particular 32K piece of code (50% of the size of the HP-71B ROMs themselves) would take lots of time to lots of skilled people and I don't think anyone would have that much time or interest for this ~30 year-old piece of code.

Well then, probably not.
