Title: EMR-resistant PC / PC-XT Model F

"This keyboard is shielded and hardened to prevent electronic surveillance from intercepting signals generated within the circuitry and wiring of the keyboard."

Apart from that it looks like a regular PC or PC-XT keyboard; the seller claims the keycaps are a bit different but I doubt that has anything to do with EMR hardening.

Seller is just good at marketing. I'm sure some geek will not be able to resist... at least be glad seller didn't try to sell some mandolin crystals, meth and marijuana along with the board.

How so?

The seller may be spinning it to appeal to someone security-minded (that isn't to my knowledge why the EMR keyboard is shielded - it's for medical equipment interference reduction), but it's not inaccurate. The EMR keyboard is shielded and it's definitely rare.

That cable is bad-ass.

I've had my eye on this one for a while, but I'm guessing someone else will pick it up now. :P

I have watched with bewilderment the steady price increase of F XTs in the last year or 2. There seem to be plenty of them, far more than F ATs, if ebay is any indication. I can see a small niche market for people who want to use them for XTant bases, but beyond that, the layout is no less atrocious than it ever was.

So what is driving that demand? Are people really using them, or collecting them?

It used to be that F ATs sold for 3x-4x the price of F XTs, and I wondered why it was not even more.
Now, it seems that XTs often change hands in the $100 range, which seems silly to me, and ATs are selling relatively cheap.

Anyway, if someone wanted a "collectible" XT, this is the one to have, because the others are just plain common.

^ This.

And for historical accuracy, EMR stands for Electronic Medical Records, not a type of interference. I kinda want to get my hands on the computer it's for, since I bet the case is shielded heavily and a neat option for a case mod of sorts.
