I found this in one of my old E-machines. I was wondering what the specks were. Not what I am running now thats for sure.

Back in 2004 a neighbour was throwing out a bunch of old computers. I salvaged the parts from them, netting some Pentium CPUs like this one and other parts (even EDO RAM!)

The fastest working combo I built from those parts contained this Pentium 100.

I used it for a while as a ClarkConnect firewall appliance. It worked well. It still works but I don't use it anymore.
