You won't be able to kill a Spectrum from any debug menus.
The +2A (and possibly B), and +3 have the following hidden menus/messages...
To invoke the Spectrum +3 diagnostic routines, first reset the machine while holding the BREAK key down. This will go into the test card dispray. Now hold down the QAZMLP keys for a few seconds unti the diagnostic title is displayed. Now follow the on screen prompts.
Also contained within the ROM is a smal message, to obtain this display, first put the machine into +3 BASIC mode and type:-
copy randomize (ENTER)
after pressing the ENTER key quickly depress the C, J and L keys together and the message will appear.
HELLO THERE I'M A +3
