Magnetic: the infamous os4 laptop that was "already running"
It wouldn't surprise me if it was running, in a bare form (the underlying kernel?), at Hyperion, with the boot security code / check removed, purely as a proof of concept. Running != usable.
Wasn't there a rumour of an X86 build too? Wasn't sure if this was developers making a proof of concept or something started on amiga.org purely to fan the flamewars...
