After recently purchasing a working card reader for my 41CX along with some new and used cards, I was debating what to use to mark my cards. I wanted something non-permanent, so I ended up using a mechanical pencil. Graphite, however, ends up smearing over time and to be honest doesn't erase too easily off of HP's magnetic cards.

On a whim, I tried one of my Pilot Frixion pens. I had purchased a few of these pens to go along with some re-usable notebooks I picked up a year or two ago. The ink dries within a minute or so on the HP cards and doesn't smear. However, the ink wipes off clean when wetted with some water (i just used a wet finger for a test).

I've got a few cards marked with the Frixion pen and will see how they hold up long term, as well as to see if they can still be wiped clean with water after a longer period of time.

Does it work on 65 cards too?

Sorry, early morning attempt at humor :-)

cheers

Probably so. I forgot the 65 had a card reader as well.

Still no clue about 71B and 75C/D...

LOL, OK, those, too. I even updated the post title for completeness.

The other nice thing about these pens is they use a bistable invisible ink. Heating the ink up by friction (using the "eraser" at the end of the pen) turns it transparent. Cooling it below -10C for a while turns it visible again!

Interesting. I knew about the friction part "erasing" the ink. Didn't realize it would come back by freezing it.

I have been marking my cards for years with a Koh-I-Noor, Rapidograph Pen set. Works great and they have different size tips.

Personally, I take a different approach as HP cards are no longer in production and will eventually become scarce. I create custom cards in MS Word for all my programs, and print to paper. I then enclose both front and back with 'Book Tape' (a thick clear tape), then cut out the cards with scissors, usually 20 or so to a page. What you have is the equivalent of the 'label cards' from the TI-58/59. They are non-magnetic but serve to annotate the user defined keys and title of the program. And they are MUCH easier on the eyes than my chicken-scratch handwriting. I keep the actual programs on unmarked (reusable) magnetic cards with the corresponding label card in the same sleeve in the card holder. Works great for me.

This sounds great John! I think it's a tad OCD, but here at MoHPC, that's a very good thing, not a label to denigrate someone. Smile

Share some photos when you have time, I think they would help to convey the feel for the process and setup you describe. We all need some way to avoid effectively rendering cards borderline unusable by our own chicken-scratching; in any case, nothing to show someone else.... Wink

That sounds like a great idea. Care to share the Word template?

Here is a sample word doc and a picture.
Note that it's best to trim around the rectangle with scissors EXCEPT to leave a little tab on the left that will fit under the edge of the window slot. This will force the labels to line up with the keys.

Enjoy!
