It was the first one I installed myself. I spent a long time trying to download all the floppy disk images for A and X over dial up. Trying to do it while on work experience on the only PC that had an internet connection made it all the more fun.
My very first as well. Had to install it to a MS-DOS partition and from there to the real Linux partition as IDE CDROM drives were still not properly supported back then.
It was the last version of Slackware to use a.out executable format and IDE ATAPI had just recently been added. My CDROM IDE wasn't supported during boot time, only after installation, hence the workaround.
