I have a P233 Slack8 machine here (no cdrom since it was salvaged into another box). I'd be willing to part with it for $75 (about the going price) plus shipping.
OS: Slackware Linux 8.0
RAM: 32 Meg (if I recall)
HD: 4 Gig (May be 4.8, once again its been a while).
I have a modem plus ethernet card in it, its not THAT old
