I remember running live and then installing from Yggdrasil in the early 90s on 486 with 8MB RAM and 250MB hard disk.

Really liked Knoppix for a lot of things, though. Used to take it to the county used-sales office and boot the PCs they were selling to test for functionality and Linux compatibility.
