Non-Maskable Interrupt. An IRQ 7 on the {PDP-11} or 680[01234]0; the
NMI line on an 80[1234]86. In contrast with a {priority interrupt}
(which might be ignored, although that is unlikely), an NMI is never
ignored. Except, that is, on {clone} boxes, where NMI is often
ignored on the motherboard because flaky hardware can generate many
spurious ones.
