Hello,
This HP-41C came in with 4 non-installed modules :
Two(2)x Memory(HP 82106A), STAT-1(HP 00041-15002), MATH-1(HP 00041-15003)... without manuals.
I really don't know how to use and install them properly.
Do they have to go in their specific locations or just really does not matter ?
Many thanks in advance for all helps,
Pyerre
