i haven't had enough coffee today!  i recently bought a little HP LogicDart
in order to do some TTL-debugging of a dead PERQ EIO board and i'm thinking
"i remember my truth tables for AND, OR, and NOT gates, but did i miss the
chapter on BUT gates?  <pause, as my other brain cell slowly wakes up> 
oh!  that's funny."

hee hee.  i'm awake now, really.

actually, i've been meaning to post lately about my latest haul - some nice
goodies to give away that might interest local rescuers.  my new $job is 
moving to a new building, and cleaned out the "back room" - i picked up a 
massive pile of stuff (filled my living room) that i'm mostly going to give
away for the cost of shipping...  gotta inventory it...
