Re: RE: PET keyboard models

Actually I am the author of that code (at least originally :-)
But I have to admit I didn't really remember the reason.
So I looked into the VICE code. The additional mappings are for
German characters (umlauts, sharp-s) - as this is a symbolic mapping,
I think there are different character- and editor ROMs for Germany,
that allowed to use umlauts, and the symbolic mapping allows to use
them on VICE too. Martin (see below) mentions them too, so I think
they are for this - not sure if that support is complete though,
in the VICE unix version you can't really select these mapping files
(from the menu, you have to browse the filesystem and know where
to find them)
