Anyone familiar with this mag card holder?
Here's an interesting recent find from an HP41 manual collection I picked up on TAS. Tucked in amongst the QRC's and overlays were two of these HP-65 Pocket Instruction Cards. Here are a couple of pictures, back and front sides, with and without magnetic cards.

I've never seen a photo or reference to one of these before, so it was a pleasant surprise to find them. They appear to be a three layer construction, cardstock printed front and back with a thinner spacer layer in between to provide room for inserting a magnetic card. It's likely that adhesive was applied to both sides of the spacer before affixing the outer layers. Note the notch in the card space opening to ease entry of the mag card.

I wish I had more of these because they look like a handy way to keep frequently used cards around and to document your own program cards. Anyone know how common these were "back in the day" when the 65/67/41 card readers were common? I wouldn't mind duplicating a shoebox full of these!

Some (10? 20?) of these were included with each new HP-65, at least in the early days of production; one of HP's early catalogs shows them (I'll look for it). I've read that at some point they were no longer included, but coincidentally enough they were still available for purchase as an accessory.

In a more than weird coincidence, I was holding one of these accessory packs about 5 minutes before coming to the Forum just now. The shrink-wrapped package likely came with 20 cards (can't tell for certain as the original seal is broken and it seems like 2 cards are missing) with a small note inserted (in 3+ languages) in front.

HP-65
Pocket Instruction Card

A Pocket Instruction Card provides two slots for program cards. You can write program user instructions in the space on each side of the card. The cards may be carried in your pocket or, after punching holes in the tops of the cards, they may be carried in a small binder. Then can also be stored easily in a small file box.

They do show up on eBay from time to time, at widely (!) varying prices, from $1/ea to$200 for a full, sealed pack.

Speak of the devil times two, Don S. pointed out a sealed pack of 20 available on TAS for under $1 per card. On their way soon! Among the bundle of HP41 manuals was an Owner's Handbook and Programming Guide. I already have one, but what was taped into the back page caught my eye. Here, in case you've forgotten, are those all-important support numbers ~Mark Who decides? 12-09-2019, 11:49 AM Post: #4  Csaba Tizedes Senior Member Posts: 457 Joined: May 2014 RE: Anyone familiar with this mag card holder?

Great deal Mark! Yesterday, I saw a new listing of a sealed pkg of these for well over \$100, so prices are really all over the place. Maybe a seller was reading this thread... lol

Yeah, I could start a separate thread on the psychology of eBay sellers and it would be months before the thread finally petered out!
