Unix or BSD for Dec PDP 11/34 and 11/45

Hello, I had asked this question on the tuhs discord channel, no response yet so i figured i would try here. I'm working to get my pdp 11/34 and 11/45 running. I was curious what versions of unix or bsd would work on the machines i have. I wanted to set up the systems with a bunch of dumb terminals and show them off at a local maker fair. If possible too, id like to be able to telnet in to unix or bsd.I was also curious if a ethernet interface exists for my unibus systems, or if i could SLIP/PPP serial to another machine,so i could telnet in as well as use dumb terminals. On a bit of a side question, did minix exist for the pdp11? There is mention of it on wikipedia, but ive not found much other mention of it. I read the minix book, and have used it quite a bit on the ibm pc, so i figured i would ask if a copy for the pdp 11 is out there. --Devin D.
