I actually think it's a good idea because it prevents a lot of
Ctrl+ALT+Delete is also good for quickly shutting off non-essential
processes which suck up resources, such as RAM when you want to do heavy
work. Microsoft Security Essentials is my usual turn-off candidate since it
starts automatically again after a while.

It says a lot about the stability of his products when he says he
wanted a one button reboot.
IBM wanted to make it an unlikely accidental key stroke.
It came from an IBM engineer designing the hardware long before Bill
Gates was involved.
You can remap a single keystroke to that code or even send it from the

I don't believe that's true. At least as I recall the original
schematics, a C-A-D creates an NMI which can't be done with a single
keystroke without redesigning the keyboard. With a USB keyboard,
you're probably right. There is no interrupt in the USB cable.

I don't think it should be too easy to delete something. I service a lot
of computer systems in retail stores and many of the users are extremely
goofy and I know they hit the wrong key 1 out of 3 keystrokes.
I can really imagine the horror show I would have to contend with if
those goofy people had a single key to kill a program. o_O

I know you can do it with a tiny COM program and you can set up a
PROMPT command from ANSI.SYS to call that program.
I used to call a soft boot in programs I wrote sometimes.
Whether you can actually put in the CAD key code in a prompt, I am
not sure. I suppose I could dig through my tech ref book and see.

Not true. The original PC keyboard had an interrupt that tickled the
NMI directly. That was the whole purpose behind the C-A-D, to make
sure you didn't reboot accidentally. Nothing else was going to stop

Pin 3 says "keyboard reset, not used by keyboard"
That is from the 5150 (original PC) book
1 is clock
2 is data
4 is ground
5 is +5v
Pin 3 may have been used in the 5100 (in the 70s) but we didn't sell
enough of those for me to ever see one.
