SLS Linux was my first distro. It was probably early 1993 when I first installed it, on a 386SX/20 with 3 megs of RAM. I think it was on 12 or 16 floppies.
I had previously been using Coherent Unix (with the enormous compendium in a thick book).
I was first setting up my home NFS server using NE2000 Ethernet cards to try all that out.
This was all run on a Gateway 386 @ 25MHz which started with 4MB of RAM.
Never looked back. '93 was the year of the GNU/Linux desktop for me.
