I know, but there is nothing Arabic on that unit, it is a UK 64 model with Arabic letters printed on the keys. Nothing more, sorry
The BRD.Rom addition was a lucky event forced by language restrictive laws on Germany just at the Enterprise launching times.
The German language was fitted as a 16KB rom on a special Basic cartridge with 2 Rom sockets instead of only one.

The good point about this approach was that the main differences between the German and the Uk units was the cartridge and the keyboard keys. The rest of the computer, including the main PCB remained without changes. In fact, a UK unit with a German cartridge behaves very German....
The German Rom changes the keys positions and some symbols, and almost all messages are translated. Also other graphics-printer oriented apps where added to the spare space to fill the 16KB Rom: VDUMP, VLOAD AND VSAVE.
The switching of the 2 languages is made with the :UK and :BRD commands.
The new commands can be seen when typing :HELP +Enter in Basic.
