I read online that there are some pins that have an internal pull up resistor and some that don't. My question is what pins...

    Pin 7 gives "Sound" like Beep without being programed.

    I have six 08M2+ picaxe chips. Every time I program one of them with ANY form or style of Program (from absolutely nothing to a 200 line program) Pin 7 otherwise known as C.0 will send a intermittent tone every second or so non stop. The only time a chip doesn't do this is when it is fresh out...
