Replacing m68k in Blizz PPC

[mrtabaka]

Hi All!

With my friend We have 2 x Blizz PPC, both were death (68k). In first we replace 040@25 with 040@40 and is working super! Now I have second one with the same problem (death 68k), I desoldered 040 and now I think about soldere 060 (EC060), not 040. It will work? Can i put EC060, need I do some modyfications?

It's a DCE stuff..


Regards..

You need to make several modifications. If you do not you will break your 060.

You need to change some surface mount jumpers.
Change the voltage regulator
Change the crystal oscillator
(Possibly change an EPROM)

I would not attempt to do it before you have not found someone who has done it successfully.

The info is kicking around the forums somewhere......

EC060 -> no !

WORK IN-PROGRESS FOR PROJECT 3 & 4.

im in the middle of upgrading from a 040 to a 060.

from my point of view it not worth putting back **any** 040 or 060 without a socket..

iv just made a socket,the glue needs two days to set..

if succesful will give tips how its done..

I just uploaded a picture I put together to help you with this project, hope it's of some use. Don't forget to flash the card. This site also have some good pointers.

The picture can be found here until my picture is processed and available on A.Org.

I've doublechecked the information on the image but if there's still anything wrong please tell.

[delshay]

any flash update i do think you need to use the phase 5 040/060 libs.


just to add: in the forums their say BlizzPPC needs fastram, or it will not boot. well my Blizzppc boots with or without fast ram,it make no difference.

im just wondering if this is why i can switch to **no precharge** on the BlizzPPC ram menu on a Overclocked board.

alexh is right, replacing 040 with 060 is much more tedious job, and it for sure requires either replacement or reflashing of the flash with correct 060 firmware.

Send it to France is my advice.  It'll cost you a little money, but its relatively stress-free.  

[mrtabaka]

There is no stress:)Replaing CPU is easy. Resoldered SMD resistors is easy too. I think that trese is no need to change flash. My friend replae 040 on EC060 in normal Apollo 1240 without replacing BIOS et. and all works super! I know a man who replaced in Apollo 1240 cpu to 060@50 and he forget hange voltage-A1200 boot's oret in 5v!But was really unstable.

[Brian]

Flashing the card IS needed when replacing the 040 CPU with a 060.

[Nickman]

But as i have read its not needed to do before puting the 060 on the card. The amiga will boot fine after the switch and you can flash the bios to the 060 version.

The amiga will boot fine after the switch and you can flash the bios to the 060 version.

True. But you need a 060RC with MMU to manage the ram and the PPC switch...
060EC lacks MMU, so ...

[delshay]

lets make things clear:

do you flash with 060 libs & flash with a 040 chip still inside or do you flash after the mod with a 060 chip inside?
