300-someodd MB hard drive, 5" and later a 3" floppy drive, MS DOS, Win 3.1.... god, I learned to write .bat files on that thing back in early grade school....
I was still stuck on an IBM XT (8088) clone running DOS 3.3 when I first started experimenting on Slackware at a friend's house; they were hoping to figure out how to set up an ISP. There was a time when that minimum 386 requirement seemed like a real hassle.
