Do Kingston memory cards have technology that prevents them from being used on unintended computers? I'm trying to use a Toshiba 4400SX 16 MB card on my Thinkpad, and it doesn't recognize the card.

No, not that I'm aware of. You may just have a stick that's incompatible with your Thinkpad (whether it's a speed issue or the density of chips or the total amount of memory).
You may have to look this up in a manual for your model because it may state the speed and density of memory you need!

What's "credit card memory"? Are you talking about Compact Flash?

Nope, IC DRAM Card. Looks like a PCMCIA card...

Try removing the card, disabling parity in the thinkpad BIOS and then trying the card again. Some cards supported parity, some did not.

The RAM cards that I have have markings on the back indicating what models the card is compatible with - I stretched the list a bit by using T4400C/SX cards on a T6600C, but the format/structure of the cards might be quite different for another manufacturer entirely. I've only dealt with Toshiba cards, myself.

It's a 755CD. I read about disabling parity in the manual, and I think I tried it. Disabling parity is config → memory → two flag-looking things next to an X, yes?
The T4400SX cards are intended to work with 6600C laptops. Here's the one that's currently in my computer, and here's the one I'm trying to install. The labels look identical, save for the product number.

My card only has the handling information on it. Where did you get the specs?
