That's a good point actually, the 68060 is hard to get and rather expensive so a more robust solution is indeed probably better.

It's a pity there are no 68060 cards with modern PC standard fan mounting holes. Would make that a lot easier.

Getting mixed messages, so suddenly thermal adhesive is not such a good idea?

Ok well that little fan and heatsink has a sticky pad on the underside of it might this be permanent do you think?

May be I should just go back to the super glue idea. Stachu said any kind of glue when I aksed him a while back about reattaching the fan I already have.

It's not that I'd say thermal adhesive is a bad idea per se, rather than the cost and rarity of the CPU might be better served by using methods that are less permanent than glue or adhesives.

Just something I hadn't considered before

I get what you mean. It's an A1200 desktop case though, room is at a premium as it is. Making a bracket might not be easy to do. And anyhow, think of the many others with over clocked 060s who have heatsinks and fans attached on top.

Funny going on the rarity of these processors which I am well aware and is partly the reason for this, but I picked up a spare recently. Let's hope it's not a fake! I trust the seller though, and he might even be on this board actually, but really I won't know obviously until it finally gets installed on an accelerator. Holding out for the ACA cards I think.

****edit**** I did actually wonder if it was perhaps feasible to attach a fan to the back of the A1200 keyboard metal plate. Was an idea I thought off when the fan first came off the CPU.

Hello, what mask do I use the 68060 to go up to 133 mhz is it possible that the 68060 reaches that high?

There isn't one. They cannot reach 133MHz reliably without extreme cooling and voltage adjustments.

It has been posted in this thread many times that the E41J mask was the last, the smallest geometry producing the least amount of heat.

So that 68060 really got to 133 mhz? regards

You have been asking this in a loop for a long time now.

Please be aware that it is not a discussion, this is just you asking question after question and people answering.

You have been given links and info. In my opinion it's time to start doing your own experiments and research now.

Yes, its time to stop feeding the troll ;-)
Does this look familiar.. I see a pattern..

I've been over this so many times over the years that it'd be nice if someone just used the search function sometimes:

http://eab.abime.net/showpost.php?p=1241771&postcount=7

No-one knows where these parts came from but they were EC (no fpu, no mmu) parts that clocked to at least 120Mhz, the clock speed limitation was due to the design of the test board on Natami and not the CPU which still ran cool.
Since Natami was getting an FPGA based CPU, and the 133 parts were always from dodgy Chinese suppliers with no official existence, there was no point in doing another board and trying it again.

That FPGA CPU is what became the Apollo Core and Vampire accelerator.

Other people have tried to acquire them and instead received rebadge 68030 parts http://warpclassic68k.blogspot.com/2...fe133-eng.html

The likeliest explanation was that these were 75Mhz 68060FE75 parts that had just been rebadged. If so they ran at 120Mhz just fine, and would have gone higher without the board limitation.

SO the answer is that no-one knows, but that they're probably dodgy rebadges...

Yes yes, but what Motorola 133MHz tomato CPU platypus 68060?

Sharks have been jumped over, time to end the thread. Thanks all for playing.
