A missing keypad locks you out of the menus

On every 6803 game before Escape from the Lost World the keypad plugs in through a single .156" Molex connector and is often lost. Without it there is no way into diagnostics, audits or adjustments, and originals are very hard to find, so a missing one usually has to be built.
