The JHU kernel was Version 6 (Research). All the development was done by the Undergraduate Computer Society at Johns Hopkins notably: Mike Muuss, Robert Jesse, me, Robert Miles, and a few others. Mike went to BRL around the summer of 1979. Any changes after that were done by BRL (federal) employees). So once you have the rights for V6 there’s nothing really additional. We did add the V7 file system as a switch but I think that wasn’t done with V7 code.

It's one of the hidden gems of the PDP-11 world. I'm not clear on its legal status so I don't know if what's there can be redistributed, but it's an extremely mature PDP-11 OS.

By the way. I’d like to thank you for mentioning the brl.pdp11 distribution below. I had despaired that I was never going to find a copy of the kernel that I cut my teeth on developing. I was able to download the set from Kirk yesterday and it is destined to replace the 2.8 BSD that I’m using oin my PiDP-11/70.

Subject [TUHS] MACRO-11
Hi all,
Do sources exist for a MACRO-11 assembler for UNIX? The only package I have found is written in MACRO-11 and relies on a provided binary to regenerate itself; it's on the brl.pdp11 archive on the CSRG DVD.
