Section 1
Using the HP 82104A Card Reader
The HP 82104A Card Reader is a very powerful system addition for
the HP-41C or HP-41CV calculators. The card reader was
specifically designed to complement the calculator system, adding
virtually unlimited data and program storage capacity using small
magnetic cards.
Note: The HP-41C and HP-41CV differ only in their
initial Continuous Memory capacities. The term
“HP-41C"" is used throughout the rest of this
handbook, unless otherwise specified, to refer to both
calculators.
Even though there are significant differences between the HP-67/HP-97
calculators and the newer HP-41C, the HP 82104 A Card Reader enables
you to use nearly all current HP-67/HP-97 Application Pac Programs, as
well as most of the programs in the vast HP-67/HP-97 Hewlett-Packard
User’s Library.
So that you can take advantage of the advanced capabilities of the card
reader and make full use of the HP-41C system, take a few minutes to
work through this handbook. You will find using the card reader simple
and intuitive, but with substantial power.
Battery Power
The alkaline batteries in your HP-41C supply power to the HP 82104A
Card Reader. An automatic power checking system has been built into
the card reader to prevent it from operating when battery power is low. If
the LOW BAT display appears while you are operating the calculator/card
reader system, remove the card from the card reader and replace the
batteries in the HP-41C with fresh size N alkaline batteries. Refer to
Batteries in appendix B of the HP-41C Owner’s Handbook and Pro-
gramming Guide.
An AC adapter and rechargeable battery pack are available as
optional accessories for the HP-41C that can be used in
combination to operate the system from line power.
