7 To enter service mode, reset keeping the service button pressed.

9 Notes:
10 - The main set has a protection device mapped at E000/E001. The second set
11 (which is the same revision of the program code) has the protection disabled
12 in a very clean way, so I don't know if it's an original (without the
13 protection device to save costs), or a very well done bootleg.
14 - The bootleg derives from a different revision of the program code which we
15 don't have.
