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) AndrÃ© -------- Original-Nachricht -------- > Datum: Sat, 7 Aug 2010 20:29:59 +0200 > Von: "Hoffmann-Vetter, Martin" <firstname.lastname@example.org> > An: email@example.com > Betreff: RE: PET keyboard models > Hello, > > > there > > are 3 different keyboard models selectable for the PET, "graphic", > > "business (uk)" and "business (de)". > > > were there infact just two ("graphics" > > and "business") and the uk/de is just for different PC keyboard > > mappings? > > There are tree keyboard, first the chicklet keyboard (original PET 2001), > then the graphics keyboard with the 20 key numpad (PET 2001-N) and the > last > one, the business keyboard (PET 2001-B, > http://www.zimmers.net/anonftp/pub/cbm/schematics/computers/pet/8032/320284. > gif).
