*edit* oh, and if you want to insert a joke, change "Lyon" to "Wien", the city where this fixed edition is from ;D
(though you probably don't live in Wien)

Aah, that's an interesting method, much simpler than the old patches for some other Mephisto devices - many thanks!
LOL, no I don't live in Wien, I'm from Gmunden (in the Salzkammergut), but I doubt that you'll know this city.
I think such a 'personalized' version would be a bit too much - OTOH maybe changing 'Vancouver' in the 'Berlin' (prototype) version would be a better idea.
