I bought Cyrix 5x86 that looks exactly like on demo pictures:



There is no part number on the chip, and it doesn't look that it was there. Printing on the back is like on normal (production) 5x86 processor. Weird stuff...

Maybe the rest of the letters disapeared with removing of the heat sink?

Hi,

I have seen more of these, maybe you can use these at 100 and 120MHz?

It could be, though I looked at the chip surface very closely and there are no any traces of letters being there.

lay a normal one next to it and see if the logos line up correctly.
