Upgrading a Blizzard 1240 to an 060.. The real thing!!! (needs translation from french)

[Jose]

Yap, some french online mag published it!
Check it out!

And if you know french help me understand the voltage regulator modification cause I didn't understand that part (yes I know some french :-D ...)

Doesn't seem to be for the fainthearted ironsolders thought.. :-o

Some people some time ago were also looking for this. Hope you find the link helpfull, now do something too, and help understand the voltage regulator part :-x   :-D
 
I should also thank the Unofficial Blizzard1260 support sitecause on my request for that info the webmaster posted an ad in the site , and after someone replyed he posted the link on the site.

Ok, lets see.

I used Google translate a bit and got this for one part, made me laugh,

Then the imbecile who writes this article sharpened his soldering iron (file) and tackled unhappy Blizzard 1240

Being serious now:

Part neeeded,
A 68060 CPU,
A LT1585 LM 3.3V regulator from Linear Technology,
3 by 1N4001 diodes,
A 330 R resistor
A 50 MHz oscillator.

IT says see picture for more info, what picture!

Take a look at this picture of a Phase 5 A1260,
http://www.amiga-hardware.com/blizz1260front_big.jpg
Right by the CPU is the LT1585 and just above the 3 regulator pins is a jumper wire, this needs to be moved on the 040 card to set 3.3V to the CPU.

The 3 1N4001 diodes need to be added to the left of the regulator as shown in this picture.

I can not work out where the extra 330R resistor goes though.

You have to remove the 80 MHz oscillator and insert a 50/66 MHz one and move a jumper by the oscillator (which I can not see in that photo).

You also need to change a jumper to select 060 for the CPU board so that it feeds the two 060 clock signals from the same oscillator (the 040 derives one from other IIRC).

I have notes on how to convert the Apollo 1240 to an A1260 somewhere, just can not find them at the moment.

Have fun.

Oh yeah, you do this modifications at your own risk. If you do it wrong and blow your card up, it is not my fault!

:lol:

Thx that's helpfull. Does anyone knows where the extra 330R resistor goes :-?

"You have to remove the 80 MHz oscillator and insert a 50/66 MHz one and move a jumper by the oscillator (which I can not see in that photo".

I thought that was the same jumper to select the 060 clock (not divided by 2). Are you sure they're refering to another one?

So, has anyone here even tried this thing? :-?

I WILL try it next week on a blizzardPPC that has now 040@25 ovcloked at 32.5 and a ppc@160 overclocked at 227.5  .
Does anyone knows where can I find the 68060 ROM for blizzardPPC I thought the roms was the same..
Also I will try to find and solder a socket for the proccessor    to be easyer to exchange again IF necessary.
Any link for the 060 rom ?

I Just managed to desolder 68040 from the blizzard ....
I Also soldered  a self made socket onto the blizzardPPC just incase I would need to change again the processor..
So now I am just waiting for the 2 68060 processors I bought from ebay to arrive.... (its from germany and it has two weeks already :-? ).
BUT.. I havent tested if the board works with the 040 on the socket because it was very difficult and dangerous the desoldering/soldering and it took MAAANYYY hours with the iron on the board.. I hope its working.. I will find out in an hour or so.
Pray for my board!!! and wish me luck.

p.s. I have made a commitment to write a tutorial about how I did it and all the phases and emotions on the experiment
 :-D

EDIT:
By the way I testit and the board is working great like before .
