I got a 300mhz PPC processor
 

I dont know anything about price of that thing.

Is it real to change it for turbo card with 68060/50 ? I want to have my amy closed from bottom (I have68040.40).

What kind of PPC processor is it ??? Those that are used in the Cyberstorms is totally different then the ones used in the Blizzards. And there´s the matter of the speed that you can get out of it. Even if you can place it for example in a Blizzard PPC, you need to overclock the card to reach 300 Mhz. Even if the processor can take it, there is still the matter if the rest of the card, like Ram, can handle that speed ...

If you are asking

The answer is yes. You have to change several jumpers and a voltage regulator but you can.

Warning Do not just replace the 040 with an 060 as you will blow it up. The 040 is 5v and the 060 is 3.3v

AFAIK there is no 300Mhz. 603e or 604 for either BPPC or CSPPC .... those PPCs are from other Apple computers and will not fit/work on Amiga turbo boards ....

There was an article in an amiga mag .... I have to look if I still have it :)

you are right retroman, the fastest is the 233Mhz 604 (only for 3/4000)!

But I have problem understanding the question! You have a 040 but want to change it to a 060 (for cooler performance), but what about the ppc ? Hehehe ..

Several jumpers as in one jumper :-)

This is written on the CPU:

IBM
PowerPC
PPC604e3BBCG330

i ask to exchange this thingie for 68060 turbocard, I assume that is not real :-(

If the processor won´t be of any use for an Amiga board and you ask for a 68060 board that will have a value between 100 and 200 GBP then ...

Well it's a shame as you could have sold it for more than it is worth if it had been useful for Amiga :nuts :shocked :lol

True, my 240 Mhz BPPC has been tuned up to 270 Mhz and that seems to be the limit ...
