Ehhh.... Cyrix MII 300 with a multiplier of 3.5 and a 66MHz bus ? 
Why do you ask?

The printing good very much, being unlike to counterfeit.
Probably the Cyrix and IDT have ever had the cooperation~[/b] |

National Semi bought Cyrix in 1997, VIA bought Centaur, developer of the WinChip, and the Cyrix division from National Semi in 1999. So it is theoretically possible that they released an MII in a WinChip package...

Thanks!~
I also notice, yellow metals of area is smaller than real MII.
This can do for the background of these chips probably an explain.
Only wish they are not to counterfeit.

the winchips were fabbed by IDT.
The cyrix's by National (and earlier by IBM)
There would have been NO crossover.
It is a fake, still neat though
