There are so many new collectors that I choose to revive this.

I need pic of the front of your Cyrix 486 CPUs, and the code off the back.

This way I can work on my Cyrix guide more.

Thanks in advance.

Hi,

I have a CYRIX 120 CPU, but I am not sure if it is a fake or not.

There are 20 different CYRIX 486's in my collection, I could scan them for you and post here, but my upload quota is only 5 Mb.

I don't understand something. Why Cyrix 586 120 is marked as PR90 Confused

I think same but 133 Mhz wasn't rated to Pentium 75 ? I would like to see 150 MHz rated to PR90 not 120 Smile

I don't know.
That's why I think it could be a fake / remarked CPU.

It could be real, as the production time is right for 120's.

the 'A' factory code is odd though (havent seen it before)
