HP41CV Strange Math/Stat Module

[pilou45000]

Hi !

First : sorry for my so mad English, I’m French…

I’ve got an HP41CV (n°2342S42063) with four modules plugged:
Port-1: XTime HP82182A
Port-2: XFunction HP82180A
Port-3 : Xmemory HP82181A
Port-4 : Math/Stat (Math-1D and stat-1B)
When I Do EMDIR the display is:
CONC P037
ATOM P045
HCC P039
473
“CONC”, ATOM”, and “HCC” are three programs that I put in extended memory with de command “SAVEP”
473 is the number of rest register in extended memory ( Xfunction or Xmemory modules) but, why 473 ?! Xfunction: 127 register, Xmemory: 238 register = 365 ?!
When I unplugged the Math/Stat module and do EMDIR again, the display is:
CONC P037
ATOM P045
HCC P039
235
Does it mean that there 238 free register of extended memory in the Math/Stat ROM module ?
And at least when I replugged the Math/Stat module and do EMDIR again, the display is:
CONC P037
ATOM P045
HCC P039
514 ???!!!
Many thanks if somebody has an explain…
