I would like to know as well.

how much do you charge cosmos for conversion? and can you put pga socket on blizzard 1240 when converting to 1260?

Your Blizzard 040 have a CPU socket ??
 
If yes : upgrade to 060 = 50 euros with a full 68060RC50 rev1 and quartz 66 (or 64) on socket + shipping back to you
 
If no : upgrade to 060 = 68 euros with a full 68060RC50 rev1 and quartz 66 (or 64) on socket + shipping back to you

Thats pretty cheap for what you have to do. I don't understand why you charge more for removing the unsocketed processor when you remove the socket anyway. Does it take more time or something?

If you see clearly on his blog article, you will notice that the socket didn't have all pins (3 rows of pins per side instead of 4) that an 060 requires.
That's why he had to desolder the socket and solder the new CPU on board.

Cosmos is the "Ambassador of Kwan" and his mods/hacks can make a grown man burst into tears lol

thanks for info, if i manage to get a blizzard 1240 i know where to get up graded

If this Blizz have a socket, I don't need to desolder the 040 => cheaper !

Is desoldering an 040 harder than desoldering the socket? I'm assuming you always desolder the sockets as the pictures you posted looked like you did. Are there some sockets you can just leave in place?

 If this Blizz have a CPU socket, of course I won't desolder the socket !?!
 
Only adding one raw of pins in the middle...

There is a picture of a board with a socket, then the next picture is an overturned board then a board with solder and pins removed. Maybe the text explains but if it's not english then I'm unable to read it.
