You sure this Lars fellow even knows what it is he's going to be exhibiting?
And why would these machines be at a Commodore show in the first place, they have absolutely not a single thing to do with Commodore.
Perhaps you've noticed that as the years go by, shows in general carry more h/w in -general-. This is due to declining totals in patrons that would be attracted to just one platform. Surely you know this.
