should have the same key code, no matter what the key top says.
When I was at IBM, I often had to work with French systems (not
that I can speak a word of it 😉), and often had an English
keyboard plugged into a French system or a French keyboard with
English.
I know that is true in the old keyboards, but I'm not so sure in
the new USB keyboards. They can identify themselves.
In this case, I would need a keyboard with the USA labels in the
keys in order to test if the international keyboard works (I don't
know the layout from memory anymore). Mine is simply not USB, but
old style, can not be connected to any of my current computers.
USB keyboard or not, they still scan the key matrix and produce the
key code, which is then interpreted by the operating system to
produce the typed letter. BTW, way back in the dark ages, I was a
computer tech and often repaired keyboards. They all scan. I even
bought a surplus Cherry keyboard with essentially a 2nd keyboard for
all the function keys. I designed & built my own scanner to use
with it and connect to my IMSAI 8080 computer (look that one up).
IBM compatible keyboards are all supposed to produce the same key
codes. Back in the days of the original PC & XT, the manual
even came with a list of the key codes.
