But, if the boards are good and the beep runs, why change them out?
Thanks for the insight on the ERR boards; it wasn't clear from the info I had seen that they, like Legacy boards, could run in conventional. And, as my post just prior to this indicates, I'm thinking of taking your advice if the newer board swap doesn't seem like it will work out.
