Went to CMU for a month in the summer of '93. He came back with a somewhat professional looking CD that had the source code for linux, the slackware floppy images, and some other junk (maybe it was SLS).
We spent a day or two installing it on my 486sx20 (which actually involved creating a bunch of floppies, and installing from them IIRC).
Not much worked, for sure X didn't. I wasn't very impressed, so I stopped messing with it. Some time passed and I tried again (possibly with another CD). I remember eventually getting X running a few months later. and probably the networking support too. Two things I remember from that time period, was my buddy impressively getting his VGA monitor to run at some resolution far beyond what it was designed for. Which then resulted in trying it on a bunch of different monitors and a number of them strangely dying not long after (the noises they made were quite memorable too). Including my buddies IIRC..
But, I didn't really stick with it other than to show it to people and mess around a bit once in a while. It didn't have any games, the command line wasn't DOS, and the few apps it had pretty much sucked. NT 3.1 which I had at the same time was more useful, but was dog slow booting on the same hardware. Heck it was slow on the screaming fast Pentium 60 we had at work. (which was also installed off floppies... all ~40 of them).
