Mac G3 keyboard problem

Hi everyone,

Uncle give me a mac g3 to format etc...
Ok,i've reinstalled on the Mac g3 the original OS (Mac OS 8.5 i think).
It has a qwerty italian keyboard.
The problem is that if i choose to use the italian layout,the keyboard
work as a "qzerty",i've change the layout to english and now i've a "qwerty" keyboard but all special character such as "è [ : ; ) $ etc" are in the wrong position.
Is there a way to have a "qwerty" keyboard with the italian layout?

Thanks in advance.

I don't know if it could be helpful but sometimes at boot it says "canno find software for "usb extended keyboard" or something similar.
