Will this fit in a standart A1200 case?
I am thinking of building my own A1200 desktop project with my Blizzardppc 240mhz and 040 at 25mhz
I am just wandering if my blizzardppc which has a 040 with a heatsink and fan, will fit Any help is apreciated |

Yes but you will need to heavily mod the case with fans and holes & different heat-sinks to compensate for the extra heat of the 040 chip.
BuZz of Exotica has a Blizzard PPC + 040 in his desktop A1200. http://eab.abime.net/showpost.php?p=436162&postcount=3 |

If you can find an MC68040RC25A with a mask of L88M that will work with no heatsink or fan. They were the last ones ever made and they run cool to touch even at 40MHz
http://www.freescale.com/files/share...cn/PCN8219.htm They are not very common though. |

Thank you very much, that is really what I am looking forward to build, with a few extra mods of my own.
I am only intrigued by what he did for the cooling of the 040, on the downside of the A1200 case. There is no picture of that place. |

Not 100% sure. You can always PM him.
I *think* he fitted a low profile heatsink & fan + drilled some holes in the trapdoor cover. But to get the airflow he put fans on the top of the A1200 case possibly operating in the opposite direction. |

Nathan/AmigaManiac have one MC68040 for sale on his site, but not mask Alexh pointed:
MC68040RC33V PGA CPU (Mask code 73F54F, manufactured in 2001, week 50). Any good? http://www.amigamaniac.com/CPUs_FPUs.html |

BTW, how do I remove the thermal paste that holds the heatsink on top of the 68040?

@alexh
Thanks for that info! I always wondered about that V suffix! I don't know why I didn't bother to look on Freescale's website, as I often do It does say it operates at 5V in the far right column. From the datasheet, a low power mode of 3.3V is "available"?: http://cache.freescale.com/files/32b...=Documentation So it seems the difference between the V and A is that the V has no on-baord FPU, like you said: http://www.freescale.com/webapp/sps/...0&fsrch=1&sr=1 Also the extra pins. Would this even plug into a 179 pin PGA socket? I sold one of these ages ago to someone, and not a peep from them. I can only assume they are using it. I would hope that they would have contacted me if it didn't fit (too many pins) or didn't work :-S I better take it off my website just in case. It looks like it is the A suffix that is the one we want I'd be interested in sending the MC68040RC33V I have to someone that has the hardware to see if (a)it can even be plugged in, and (b)if so, does it work? Any takers? Of course, I would want it back regardless - I will pay all postage/shipping costs, so it won't cost any money for the (also) curious soul. Nathan |

Actually, if I remember correctly, I ordered this part for someone, but he didn't buy it because I took too long to get it Either that or he realised it was the wrong part. Oh, the shame!
