[net.micro] NCR-PC XP button, what is it?

skip@ubvax.UUCP (Skip Addison Jr) (02/01/86)

I have an NCR PC/XT clone here with 8086 processor and hard disk.
On the front between the speaker volume control and the power switch
is a button with built-in light.  What is the function of this button
and/or light?  I'm totally at a loss.  The label under the button says
"XP".  This unit came without an Owner's Manual, which presumably also
has NCR's customer support number, if they have one.

Thanks for any help.
