In my halcyon Amiga days of yore, I learned about this from a magazine article (INFO? Amiga World?) about a University (Georgia Tech?) installing a labful of 3000UXes. Owning just a well-expanded 2000 and without the funds to buy AMIX, I discovered NetBSD, though I needed to trade out a 40 MHz 68EC030 (without MMU) on my accelerator card for the MMU-enabled version. I remember it took the better part of a week, and constant retries, to get the full install sets and kernel. I ran that rig all the way to 1999, junior year of college at UIUC. Good times.
I still run NetBSD on a personal machine (and a toaster).
