Donn, I've no doubt there'll be no regrets, and in the next week or so you ought to be gettin' a Check fron S.E. Arizona. I taught Electronics Assenbly back in the late '70's (Soldering, Wire Harness Assembly, which included Lacing to Mil Spec., Component ID etc.) and Semi Conductor Wafer Fab, mainly Die attachment and Wire Bonding. And there wasn't a Class that pased that I didn't learn more than the Students! Almost always as the result of a question where I when "Huh??" and had to think way through someting or other I never worried about before the question.
