My main machine is a 2.2 Ghz Celeron / 512mb ram that is running Win98. I also have a Pentium II (450Mhz) / 256mb ram that is running Slackware 9 that I use for programming and a Pentium III / (600mhz) / 512mb ram that is running FreeBSD that I have just really started toying with. All of these were given to me by family members who upgraded except the Celeron machine (I built it my self )
