I don't know the specific timings of the keyboard controllers, but one generally has to wait for mechanical switches to stop bouncing. The contact is not a clean one, but rather a series of brief contacts as the contacts close, then bounce a part, then close, then bounce... This continues until the spring finally overcomes the switch bounce. -Chris -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
