Working fine with original Kickstart 3.0 and 3.1

Two case for the installation :

1/ you have a 68040 already installed : only remove it, and plug the 040/060 adapter. Remove the original oscillator and plug the 100 Mhz one. Be carefull at the dot, see picture (red arrow) !

2/ you have a 68060 already installed : you have to put back the CyberStorm into the 040 state. You need to switch two resistors, remove the onboard regulator and move a JMP (http://leblogdecosmos.blogspot.fr/2011/01/mkii-040-060.html). Remove the original oscillator and plug the 100 Mhz one.

Is this working for MK3 too?

I need to try !

First, it will be with the Mozart version because of the Simm sockets !

Ok, I did more checking, always with Quake 1 because the game use the Fpu a lot...

After many time of Quake running, maybe 1 hour 1/2, the Amiga 4000 crash...

The temperature is still quiet low, about 40°...

Not all 060 rev6 are able to reach 100 Mhz without issue : some yes, some no...

So, I tried with a 96 Mhz oscillator with two rev6 here, and still same issue...

When I use at 96 or 100 Mhz for every days software, that's ok !

When high calculations with the Fpu during more or less two hours, the Amiga stop working...
