I got one of those Christmas packs that came with the German Keyboard.

Although I haven't tried yet, it should be possible to physically re-arrange the keys to transform it into a QWERTY keyboard.

My question is, how do I change the Keyboard to QWERTY on the OS_

Thanks

In AmigaOS preferences-locale settings usually have a country - general language and symbols prefs. Keyboard should be in input  or amigainput - keyboard type.

This is from Hyperion Wiki on OS 4.x, but should be similar or same in OS 3.x

For those using ApolloOS:

Open "ApollOS"
Click "Prefs"
Click "Input"
