That's because it's a hardware problem in the external keypad. The only fix that we could possibly do would end up costing as much as a new Mac Plus keyboard. If you don't need the keypad, disconnect it and everything will work fine. For all you hardware hackers, the problem is simply a matter of timing. Unless the keypad is constantly given an electronic whack on the head, it will occasionally hold up a signal long enough so that the Mac Plus won't get it. When the machine boots or a long floppy disk access occurs, it's possible for the keypad to "fall asleep". That's why the Mac Plus came with the keypad and keyboard in one unit. _emt
