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...
