Found in a drawer today while looking for something completely different ...

Left: Red Hat Linux 4.0; Right: SuSE Linux 6.3

Red Hat 4.0 is, I think, the oldest version of Linux for which I own media. SuSE 6.3 (correct capitalisation for that version) was the first version of [open]SUSE I used. I was given that set of media when I went for my interview there around Christmas 1999.

Now, to see if I can find some really old Slackware media to trump them, I know I have a floppy disk box somewhere...
