Here I got fully working Pentium 3 733mhz CPU and you know how hard is to
find P3 slot 1 cpu running above 600mhz?! Well trust me it's hard.
This one is from some IBM desktop motherboard which I have for ages sitting in my basement.
My wife is mad about this babies I was collecting last couple of decades, they are taking up space.
I got rid of it.
Cheers.
