What's the most obscure distro you can think of

I ran yellowdog on my PS3 until they took away the otherOS

Someone gave me a PowerMac and of course I had to try to run Linux. It was an interesting experience, it would boot to MacOS and then run the Yellow Dog bootloader. Couldn't get it to boot directly. That little experiment showed me how tightly Apple controlled what would run on Apple machines back then.

That was the my first distro. Getting it to run off a FireWire drive was an interesting introduction to Linux.

Fun fact: yum stands for Yellow dog Update Manager. I know it's been replaced by dnf but I still think that's cool.
