Great. Another article on old Linux distributions that's just the same crap as in all the others.
FYI the first picture, the one with the 0.12 boot & root floppies that is in every old Linux distro article, is the original distribution made by Linus Torvalds himself. Two releases later, 0.95a (3/17/1992), Jim Winstead started doing the root floppy. H.J. Lu's "bootable root disk" came shortly afterwards. (9/23/1992)
When you see an article with that picture labeled as H.J. Lu's boot/root floppies, just stop reading.
I don't know if anyone cares, but at ~9:15 there is a PDP-7 shown. To the right Max Mathews is shown sitting in front of a display with I assume MUSIC IV on it. This would make that PDP-7 part of the Graphic II terminal made by Bill Ninke. It is this PDP-7 that Unix is later written for/on.
So I believe this specific PDP-7 (serial number 34? It was the only one shipped to Bell Labs with a display before 1969.) is what would later become the "Unix genesis machine". Unfortunately, I also think this is the only footage of it, at least online. Anyone care to correct me? Please.
There is also a torrent ( http://thepiratebay.sx/torrent/7978965/ ) which has the ones at archive.org and more, with some replaced with higher quality scans. And ftp://helpedia.com/pub/archive/temp/Byte/ has some that aren't in either the torrent or archive.org yet.
z/VM, z/Linux (bare metal or under VM), z/VSE, z/OS, and I believe z/TPF. That's the newest stuff. It will also emulate 360's. I think the first thing I ever ran on Hercules was OS/360 MFT! Anyone can legally run VM/370 and MVS 3.8(?) and anything older. Oh ya, MTS, Music/SP, etc. too.
That damn XKCD is overly simplified at best. I really wish people would stop linking to it.
