I remember ghosting being a practical problem in the 1980s when people used the keyboard as a game controller. The other keyboard problem was debouncing. (Glad to see the spellchecker knows that word.) The proper way to debounce would be to have a key switch with three terminals. Cheap home computers didn't do that, obviously. Do modern keyboards do that? I should have taken one apart last time I had one to throw away. Next time!
