Roughly about 92/93 is when I got my first exposure to Linux, but had been using older legacy UNIX systems which were accessed through the dial-up VAX systems at the local uni.
First distro was SLS Linux, as a buddy was a C developer for a UNIX house. They had been gifted a copy from SoftLanding for testing for possible future developments. It was usable, but pretty rough. You could bypass the login, by simply holding the backspace key (removing the login prompt) and pressing Enter.
Ran it on a IBM PS/2 for about 6 months, before moving it back to DOS.. then about a year later moved to Slackware, when it become available through Usenet.
