It clears the key flag, but only if the key is not still pressed. It does not clear the keycode register. They are two separate things.

Quote:what exactly is the value of the KB register for each key pressed? Is it a scancode of sorts that's common to all Voyager units?

Same on all Nut-based Voyagers.

See the keyboard section of the Nonpareil 15c.ncd.tmpl file, starting at line 187.
