I think OS4 CAN be run on MAC MINI (USABLE)

[Trev]

The Mac stuff is fun, but I still say OS4 needs to run on a PS3. The hardware is cheap and plentiful.

Well, not the Wii. The PS3 was designed to run multiple operating systems, and apart from hardware-banging graphics, can be used as a general purpose computer without legally questionable hacking.

Realistically, legitimate use of OS4 on any non-Amiga platform will require a bit of indepedent development. Regardless, pushing for Mac PowerPC support is just as bad as pushing for continued support of the AmigaOne. They're both dead platforms. Besies, a decent used Mac Mini costs about as much as a PS3 anyway, and it can't run PS3 and Blu-Ray software. ;-)

I was thinking along the lines of positioning OS4 as a platform for parallel processing. While certainly not a new thing, it had gone by the wayside in mainstream distributed systems until we'd hit the practical speed limit of current technology. Anyhow, there's plenty of room for competition in this space. That said, OS4 is basically 80's operating system technology on a newer platform. Maybe it's better off consigned to single-CPU systems? (Cue the custom chip and dedicated processing unit discussion.)

EDIT: I think MIT has some public course materials availabe re: porting operating systems and software to the PS3 (and Cell in general). Should be interesting reading, even if you don't plan on putting fingers to keyboard.
