This processor was around 800MHz I think.
The PC was auctioned at a surplus sale that the BSC Vocational Center and my friend Jeremiah was at the sale. He didn't know what speed it was but did know that it was a Duron so I looked up that processor and was VERY excited to be able to get it for some price ($50?) even if it was the slowest model.
This lived in my clear case (almost all parts built of clear plastic). Maybe the Pentium II system did too?
