In that sequence I've never experienced an MMU reset (well, *almost* never). I believe there is a warning in Monte's build document about not removing the jack while the calculator is on because a momentary short is created when pulling the jack from the plug. thanks Mark. Yes, that's exactly what I do, too; I should have noted in my first post that the 41CL is always OFF when inserting or removing the cable at either end. It's odd that you don't see it, then. Perhaps small differences in spec over time, or just bad luck. Not a big deal, as I said. thanks both for the replies.
