Are there any pin compatible members of the PPC family that offer greater speed then the ones found on the blizzard? Or even simply ones that don't require honking great heatsinks on (comparatively)?

No-one is OBLIGATED to help anyone.  If someone got banned for that, than thats disgraceful.  If they got banned for something more than that, thats different.


Quite so.

The poster in question was challenged on his attitude (he wasn't just not not helping, but stating that although he knew the answer he wasn't going to tell on the basis that it might give some kind of competitive advantage for some supposed future project or some such). He then went all Vesuvius and got b& for delivering possibly some of the most childish and obnoxious behaviour I've ever been witness to on here (including my own, so you know damn well how far down it must have been).

It's more plausible that it could work the Cyberstorm accelerators.  But I think you're right, it's definitely not going to work with the Blizzard designs.  This is because the Blizzard designs are restricted to a 32-bit wide bus.  I fail to see why they designed it this way, given that they already used a 64-bit design with the Cyberstorm.  The only thing I can think of is that space limitations on the Blizzard PCB prevented them from routing a 64-bit databus, so they had to resort to a 32-bit bus instead.  I'm not sure how many layers the Blizzard board actually is.
Space restrictions will have been less of a problem on the Cyberstorm boards because they didn't need to fit inside a trapdoor.


If I were to guess I'd say as a cost saving measure as much as space saving - those cards were hideously expensive as it was, not to mention complex.

Maybe it was a mistake for me to restart this thread, after all.  All people want to do is discuss the merits of the events that occurred on the old thread!

Not at all sir, getting it out in the clear in a calm, pleasant manner is a valuable and useful thing. Tbh I think it's all done with at this point anyway.

But wasn't the form factor changed?


You're also not taking into account the fact that later embedded processors are direct descendents of the 603 and 604. IIRC the cpu in the Sam is based largely on the 603.

It may well be that there is some obscure part number floating around out there that is pin compatible with the 604 (and 603 for that matter).

@Methuselas

I always try for funny if I can, simply because I find it gets the message across to the wider audience much more effectively then playing it cold.

tldr; I do it for the lulz. :D
