I no longer call myself a slack user... however....
I cut my linux teeth on slackware. I'm guessing it was around 1995[*1] or so, driving back and forth to the local community college with my dad for EMT classes, we'd bring a few boxes of 3.5 inch floppies, with scotch tape on them... each piece of tape had some archaic symbols drawn on it like X3 or KRN2... while he was in class, it was my job to connect to a mirror and grab those floppy images. It must have taken us 2 to 3 weeks to get a full working install with X. Occasionally, we would splurge and dialup(14.4 baby) and download a smaller image or two to install something.
At this point, I had a triple boot box, thanks to lilo. I could boot Sco Xenix, Microsoft Coherent, or Slackware Linux!
After having been through that a few times, we ordered the walnut creek disks. I still have them! Those were the greatest thing ever made. All you needed was a boot and a root disk to install slack! no 60 floppies for me any more!
1. I remember the migration from 1.0.86 -> 2.0 kernel, because the whole 'ELF' binary thing confused the crap out of me... but don't remember where in my linux life that happened.
