Most powerful PPC that can be put in an A1200?

[Iggy]

Fastest is 380Mhz with very high speed memory access,but I have a strange feeling 400Mhz+ will soon be reached.

That is a 603e, isn't it?
Didn't know you could push one that fast.
The fastest I remember Freescale making was a 300 MHz unit.

Not exactly a power house regardless of speed.

Might make OS4 more tolerable on legacy machines.

If it is a 603e processor at that speed I can assure you it can go faster. Its not about the CPU,its about memory access speed.  

The Blizzard mini PCI slot is also dragged into this.

The next jump if any will take the Blizzard pass 400Mhz and beyond,but im almost certain 400Mhz+ is not far away.

If the Blizzard card hits 500Mhz+ it will certainly raise eyebrows for a classic computer.

I'm not 100% sure about the CPU (that was just from memory - and I've never owned one).
Yes, getting a computer that old up to 500MHz would be an accomplishment.
Pity no more of these cards are likely to be made. Freescale list the entire family as EOL with no replacement.

I remember many years ago some mentions that some version of the G3 would be feasible as a replacement in Blizzard cards, but given the value of the Blizzards I guess it's not worth the risk and apparently noone has seriously tried.
I've lost interest in the Classic PPC stuff after getting a Pegasos G3, an A1200 for old games and programs is great but for more recent apps / productivity it's a waste.

I feel for you there.
G4 Apples and an A2000 satisfy most of my needs.
You guys do realize we're talking about working hard to get G3 performance.
Man, we DO discuss some odd ideas.
