Mask Revision 1 Of The 68060 Processor Series Question

[CU_AMiGA]

Hey Yo!

The Blizzard 1260 i own was made in 1994/95 and has the revision 1 68060. I have heard that the revision 1 of the 68060 has problems (bugs) with the Store/Load Bypass option, so i have disabled this option on my startup sequence. The question i have is that would this affect my system in anyway (any slowdown?) and would it be possible to put a higher revision 68060 instead of the one i have got already.

Regards,

Hey Yo!

Here is what i have:

14.RAM:> cpu060
System: 68060MC Mask 0-1f43G,2f43G-0g65V Revision 1
Settings:
(INST: Cache Burst)
(DATA: Cache Burst)
(BRANCH: Cache)
(Superscalar)
(WriteBuffer)
(Store/Load Bypass disabled)

I will enable it again until i get problems. What problems will i get though (if any)?

Regards,

-EDIT-

I am not really up for overclocking, as i am using desktop now :-) Would it be possible to swap 68060?

I dunno, any "problems": Crashing, freezing, Programs not working, scrambled screen, anything. If Amiga hisses or growls at me, that is also a "problem" :-)

Hey Yo!

I don't want to sound like a complete idiot here, but i forgotten how to enable the Store/Load Bypass thing. Ocording to my notes, i used a "cpu060 nstb" command in my startup sequence. But i couldn't find it. How do i enable this bugger then.

Oh, and i will look at that 68060fix document as well, thanks.

Hey Yo!

After much deciding, i think i will leave the store/load bypass thingy disabled. I got a little fright when bloodyhound said it would affect a 1/4 of my Amiga speed performance.
