I have a strong emotional connection with Slackware. I downloaded everything except X11 via my family's 2400 baud modem in the early 1990s. I was amazed to have Emacs and the GNU compilers on my own laptop. 6months later I bought all of Slackware on about fifty 3 1/2 inch floppy disks and I was in heaven.

At the same time at work, I was building systems on top of SCO Unix, which was good enough but expensive.
