It is, as funkytoad writes, an AZERTY keyboard rather than a QWERTY. It also uses symbols instead, eg of 'option', for some modifier keys. I have a German keyboard from my PB160 with a German-localized System 7.1, as it was received, which could be called by analogy a QWERTZ keyboard. It also has symbols instead of lettering for caps and some modifier keys. Both AZERTY and QWERTZ have only four keys to the right of the space-bar.
