Reason? So the Peanut user could mess up his modem and floppy transfers by
banging on the keyboard at the wrong time? Maybe to make sure that no one
would try to hack in an 8087 NDP?
I wonder if it was because the chicklet keybard had no internal buffering,
so NMI was thought to make it possible to grab keys as soon as they were
hit.
