Did the Poseidon author reject the official announcement then, apart from the Poseidon registrations end ?
I would when such an announcement was written on their website and across mailinglists.
like you say yourself a lot can happen in a year and the announcement from Elbox magically working on a SharkPPC is also long time ago.
Didn't Buck say OS4 works on the Pegasos ? Does Hyperion have a Pegasos, no.
