I just had a thought, I'd laugh my ass off if this OS4.1 install disk just happened by pure chance to work on an Efika. :-D
Could you just imagine Amiga Inc complaining to the judge that Hyperion released a disk for new and existing hardware while Hyperion's lawyers just stand their with stone-like faces and their fingers crossed and hidden behind their back saying "We were as suprised as anyone when we found out it worked on the Efika! You can't think we did it deliberately because why would we adapt our software to work on a non-partner's board?"
Nah, we couldn't be that lucky... could we? ;-)
