I have seen keyboard lockup cured by unplugging and replugging the
keyboard.  I have done it myself.  I *do not* suggest that you do this,
I am just making the information available to you.  This quite possibly
could damage the keyboard and/or computer. I believe that it is the ROM
firmware messing up the CPU in the keyboard, since (a) the two cases of
the problem I've seen have only been under DOS, using the BIOS, and not
under CCPM or UNIX, and (b) one was cured with a new version of the
BIOS.
