There are a couple of ways to use the Apple Desktop Bus British keyboard
with a United States system. Both involve modifying the System Software
running on the Macintosh.
The first method is to install the British System software on the
Macintosh. This makes all of the necessary resources available, so you can
use the machine exactly as you would in the UK.
The second method is to take the necessary resources from a British System
Tools disk and install them in the System file on the Macintosh in
question. If all you want is to map your keyboard properly, then you need
the British 'KCHR' resource. You can use ResEdit to transfer a copy of
this resource from the British System to the System file on the Macintosh.
Once you've done this, choose the British keyboard mapping through the use
of the Keyboard CDEV in the Control Panel.
If you want British sorting as well as British numerical and date formats,
then you must copy all the British "itlX" resources too, where the "X"
includes b,k,1,2,3,4. At this point, you would probably do better
installing the British software, because the international software
typically includes keyboard mapping for US keyboards, too.
Either way, the keyboard will function properly with a Macintosh
manufactured in the United States.
