Blizzard PPC604e upgrade discussion

The fast slot can not address more than 128 megs of ram.  That is why there is a 128mb limit on the A3000/4000 machines.  Not sure if any type of software/hardware mods would eliminate that since I dont know the acutal reason for the limitation.  Amikit will have that new Z3 ram board for sale soon.  

Also it seem that Amiga OS classic can't deal with more than 512 megs of ram in any senario.  Again, not sure if that is a hardware limitation as well, could be a Z3 bus issue as well.

I have a Cyberstorm MK3 that was a PPC card that was repaired and made a 060 card only.   I wonder why the PPC side dies?  Can they ever be made PPC again?

For multiplexing, would a line from the Amiga MB to the fast slot card have to be added?

I think it has to do with expansion.library and reserved space for Z3 addressing, autconfig etc etc..

The thread on a1k.org on the new ZorRam expansion says 512 megs is the max they can get working including chip and onboard fast ram.

Here is the thread they talk on a1k.org that links to amiga.org about regarding the memory limitation.
