68030 and Blizzard IV

[DyLucke]

Hi there guys, i've wondering if our 030 accelerator boards would accept an M68030 (the full version) instead the stock EC030.

Maybe if we can install one of these we would not need to go for some 68882 FPU? Or it would be impossible to take part of the embedded FPU in the non EC 030?

Cheers!

Erm, i always have some kind of dislexy when talking about this... I tend to mix the terms FPU and MMU that are really different from each other and different devices...I'll restructure my question. I've heard there are some 68030's that have embedded FPU working, if that's so, would one of these work on the PGA socket having all capabilities? or as long as the design of the Bliz card has a dedicated FPU socket the FPU inside these "hipotetic" 030's would just not work?

This way is more clear i guess... And maybe these 030's are just gossip...  Or maybe what i heard about is some 030's have non MMU... EC then? :-D  I was just curious about it.

Arrgh! messed again!!!
Could somebody clarify me this point?

Got it. So FPU embedded is ONLY for 040 and 060 series, what an EC030 has not is Memory Management Unit, not Floating Point Unit. FPU for 030 is always external 881/882 PGA or PLCC socketed.

Well i do need an FPU for Mac emulation you know, w/o it video is quite slow, but FPU can do quite C2P process...

I don't know how, but i messed AGAIN the terms so i came with this post... I guess i will need to write IT DOWN to not forget it again...

EC = NON MMU

Thank you guys  :-D

Aaaaargh!

See? THERE i go again

It seems i messed again MMU with FPU...

I've read time ago about these video drivers, like Savage or TurboEVD but i MESSED it again...

Thank you for the rectification Piru... I guess i'll need to be careful everytime i read about these two again, if not i will mess it up again... as usual...
