Heh! I did that too. I had a old 486 compaq server.. a old job with a SCSI hot swappable drive array.. and a EISA bus. Ancient, obscure, I had to wait 2 months for somebody to make a custom driver for it and it took me another month or so to figure out how to use it, but I got it installed! You see the EISA bus was a weird one, not to mention all the hardware was compaq propriatory.
however I am lying a bit did have redhat installed on a previous computer.. I used it for a NAT firewall/router for a DIAL-UP connection. I had it set up so that my roomates upstairs could activate the dial up proccess from their windoze 98 machine. It would also disconnect (sometimes) from a incomming phone call, and it had little idicator lights on the taskbar so my roomates could see if it was connected and they could disconnect it it they wanted to make a phone call. I did that all with a generic version of a lucent winmodem. (PITA) And the crappiest RD distro of all time: 7.0
I did that to end the 1 phone line, one female upstairs, one quake player downstairs wars that were building up.
