History

“As the HP-67 and HP-97 had an embedded card reader, Hewlett-Packard could not omit to give to its flagship, the HP 41C/CV/CX family, a peripheral completing its continuous memory feature to backup and restore its programs and data on an external device. Taking advantage of the 4 I/O ports of the 41x system architecture, Hewlett-Packard had the good idea to provide a smart optional disposal, easy to plug in the HP-41, to save and restore programs and data on small magnetic cards. The Card reader (and writer) was born. Because the magnetic cards designed have a capacity of 224 bytes, the Card reader keeps track of cards as they are read and prompts you for the next card when necessary. A security feature is also provided to allow a program to be run but not reviewed or altered through normal operations (protected media). Eager to provide the best possible service to his HP-67 and HP-97 clients, Hewlett-Packard included in its Card reader all the necessary instructions to ensure the compatibility with the magnetic cards coming from the HP-67 and HP-97 calculators software library.”

Condition

The HP-41 Card reader presented in this auction is in excellent cosmetic and working condition. I tested the Card reader by setting flags 1 to 4 to ON and executing a WSTS instruction and, as expected, it required me to insert a magnetic card for a writing operation. After that, I set flags 1 to 4 to OFF and read the card. After the card was inserted and processed, flags 1 to 4 recovered to ON as recorded on card.

Ö               The card reader box is in pretty good shape,

Ö               The rubber foot show minor wear,

Ö               the latches maintaining the card reader to the HP-41x are perfectly operational (often, one or both are broken at the level of the rotating axe),

Ö               the wheel pulling the card (made of rubber and disaggregating after a time) has been replaced in 2006 by a 2 round O rings (square ones exists too), thanks to Mark Hoskins (waterhosko). I did not glue the rings to the axe, they will be this way easily replaceable in the future if it becomes necessary,

Ö               no scratch and no engraving,

Ö               the magnetic cards wallet is in very good condition,

Ö               the 40 magnetic cards including one abrasive card are unused except the card 1 used for tests purposes,

Ö               the HP 82104A Card reader Owner’s Handbook with no page torn nor engraving (except a phone number on page 1) is in good condition only; it would have been rated as very good without this phone number and a SATTI company sticker on front cover page,

Ö               the HP 82104A Quick Reference Card is in excellent condition,

Ö               the subscription form is in excellent condition.

 

NOTE regarding card reader and magnetic medias:

- O rings are not forever; their intrinsic characteristics evolve in the time, becoming dry for example; consider the eventuality of changing them again in the future.

- When unused, oxidation may appear during the time on card reader contacts in charge of card insertion detection, avoiding the card reader motor to start; testing it one or two times a year can mitigate this problem.

- Magnetic properties of a media depend on media quality, storage environment condition and/or manipulations.
