   Well, I ran into a very unexpected glitch.  ACE Hardware sold me a 
not-just-used-but-smoked outlet.  In a new, sealed box.  I'm not quite 
impatient enough to pull one out of the wall, so I'll be up on jacks 
till tomorrow evening.

   Bummer about the keyboard.  I hope it's an easy fix.  To tell the 
truth, keyboard problems are one big reason I lean toward systems that 
can run with a serial console.
