Yes, it does. (It would have to to avoid GETting the same keypress over and over.) The only way to sense the keyboard from Applesoft without clearing the strobe is to PEEK it. In this case, it is PEEKed to avoid waiting at the GET when no key has been pressed. -michael NadaNet and AppleCrate II: parallel computing for Apple II computers!
