We all know what Hyperion's response will be: that they haven't recieved a Shark yet


Erm... Exactly.

Maybe they are planning on doing the hacking themselves?


Ah, yes, the "magic compatibility" story... They can't hack it themselves. Even if they'd manage to make it run, it would be highly illegal...

A PPC CPU is a PPC CPU afterall.


Quite the contrary. The CSPPC and BPPC kernels lack the support for any other CPU but the 603/604. The Blizzard and Cyberstorm have unique interrupt controller logic. Plus, anything like that Shark would be a PCI card and I doubt it will have direct access to the custom chips. This will not run unmodified.

And even if they'd manage to build a complete Cyberstorm-Lookalike, the L2 cache and special features of a G3 (or G4) CPU would be unavailable, because, as I said, the classic kernels lack the CPU support for these, and the AmigaOne version will require an AmigaOne mainboard (complete with VIA southbridge, Intel interrupt controller and ArticiaS north bridge).

There was also the controversy over P96 Voodoo drivers and the ongoing lack of info re OS4 and SharkPPC. On one hand we have Elbox saying "we're waiting for the software" and on the other we have Hyperion saying "we've not been approached, OS4 won't work with the SharkPPC".


I don't know if Hyperion has been approached or not (I think I would know if we have, but I don't need to know all the details ;-) ). However, either Thomas or myself would be the person to make the adaption, i.e. the guy that gets the prototype hardware to stick into an existing Amiga to actually make it run.

No, it won't run automatically. You cannot just put the AmigaOne version on the thing (unless you adapt the boot loader, it would fail with such trivialities as the layout of the U-Boot data structure). Even if it would be made to run, it would be completely illegit unless there is a license for it.

Bottom line, no, unless we get a SharkPPC to actually do some work, nothing will happen. If they want to wait until OS 4 is finished, that's OK with me, but it will surely take some time to make any sort of adaption (one months is the rough estimate I've given before) so I don't really see the point in waiting for a final release.

By that rule, OS4 is vapor too.


You can actually buy it.
