Could very well have been Slackware. Slackware was my first Linux distribution, it came as a set of like at least 20 floppies. All of mine were repurposed AOL disks. After spending about a solid week or so downloading the whole set of disk images over a slow and intermittent dialup connection, the next most painful thing was the fact that floppies were notoriously unreliable. Some disks would throw I/O errors when writing. Some would get caught immediately after when verifying. Many others showed no problems until install time. Getting two dozen floppies to actually read 100% of their contents successfully took a week or two on its own because I only had one computer to work with.
