RE: 41CL MMU disabled when unplugging serial cable
I always power off the 41CL THEN disconnect the serial cable usb from the pc THEN remove the serial jack from the 41CL. 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.
