I actually have one of these, though mine's currently offline until I get a CF card for it. Will be trying out installation with an Artmix PowerMonster adapter when I get it all back together. I've been running NT 4.0 PPC on it, it will install from the stock CDROM, but you need a 2 floppies, one to get the ARC loader for the platform installed and another to load the machine-specific HAL. The nice thing about NT is it has wider PCMCIA support. However, if I could ever get AIX 4.1 media, I would love to play with the video input on the 860 - all the documentation I have found implies it is only supported there. Linux is another possibility for it, though I have not tried that since the 2.2 kernel or so. I know platform support for PReP is getting rusty there.
If you don't have a floppy drive you can build a custom NT4 install CD that includes the ARC loader and HAL for it - I have instructions for making that somewhere.
