We have a blit emulator in 9front: http://code.9front.org/hg/plan9front/file/3595611ca650/sys/src/games/blit
There’s a lot of stuff in these versions that would eventually become parts of Plan 9. mux eventually evolved into the windowing system, and I’m pretty sure /proc and sam appeared as well.
/proc on v10 and Plan 9 are different, both in scope and implementation. Sam, rc, upas, and faces are direct descendants though.

I wonder if there’s any commercial market for old Unix versions these days, or if they’re just worried there might be and they’re leaving the door open.
Definitely. There’s companies still running PDP’s. At least one still uses Xenix. A bunch use SCO OpenServer, the legal heir to UNIX name. Big in inventory systems. I have no idea what value of this is, though. My just be a reflex from legal department.
Though who ran post-7 AT&T Unix and didn’t migrate to Plan 9?
I don’t know if any did. I’m saying enough ran worse or obsolete stuff that someone might be running it, too.
treasure troves of C UB.
