How to replace a 68060? (CS060 MK1)
One of the youtube clips I found seemed to indicate that the 68060 is simply pushed down into the socket. I think that applies for my CS060 MK1 too. Correct?
The tool used to replace it looked like a cross between a spatel and a fork - approx the width of the whole chip. What tool is that, and where do I buy one? Are there any reputable places to buy a Rev 6 (that is the bug-free one, yes?) full MMU/FPU version? I don't need the highest clocking ones, I will run at the stock 50MHz. Thanks. |

Any rev above 0 is the bug-free one, so if you're just going to run at 50MHz any rev will do except rev 0. Later versions will run cooler so you won't even need a heatsink on them at 50MHz. Rev 1+ will be fine for you. I have a Rev 0 which in normal usage there aren't any noticeable problems with but it does run fairly warm without a heatsink.
Really you don't need to pay the premium for a Rev 6. |

Forgive me for being dumb but you are talking about the Cyberstorm Mk1 yes?
I have one here, unknown working or not as I still slowly restoring an A4000. I was wondering about how you get the cpu out, not that I plan to do that unless the card is non-working. But I will probably get somebody who knows what they are doing to repair if things go that way. |

I had my 68060 barf on good code - and the workaround makes it slow down - so I want to replace it with a known working bug-free one. If ebay is an indication then prices have gone silly. |

Regarding the tool used to remove the cpu, do you have that picture handy? There is a chap called John Hertell who has done some insane things with A3460's cpu cards. His recent work turning these into 060 cards, somebody added a zif socket for the 060 cpu which means it can be swapped at will with hardly any fuss! Either that was John or somebody else's work. But I think its genius I am probably running ahead of myself with all this! but I am tempted to look into this stuff |

(And I haven't ripped apart my CS060 to check if the pins are soldered...) (Oh yes, still looking for somewhere to get a Rev 6 060!) |

I got my processor removal tool packaged together with an Intel Pentium III 1GHz Coppermine CPU I bought to install in a new motherboard.
The motherboard has a zero force insertion processor socket, so I have never needed the tool with that processor. (It is now in my Amithlon / AmigaOS XL machine . ) Edit: I don't know whether the tool was available separately. Mine was packaged complete with the processor in a box much larger and more rugged than was necessary. Last edited by prowler; 03 November 2017 at 00:30. |

Wide flats headed screwdriver, slowly and carefully work your way around the cpu corners to ease it up a mm at a time.

There's a screw based PGA puller tool too, which is the safest way to remove these, but it seems they're a bit hard to find in 2017.

I got it done, but it was a bit of a cold-sweat thing. When it first had lifted a little I used a tiny screwdriver that I put between the pins and jacked carefully.
Putting the new one in was worse though. At one point you have to do a leap of faith and just push, hoping all the pins had been massaged into place. |
