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.

Yes. The MACRO-11 we have is written in macro-11....
https://github.com/andpp/macro11
Is in C++, but I don’t know how good it is.
I also think the pdp11 binary is on the 2.11 tapes since Harvard LISP
depends on it. Also on different USENIX tapes.

decided that they did not need to provide some sort of README or INDEX for

Amen. Says the guy that wrote the nselite source management system in 90%

It’s not written in C++, just plain C.

Yeah, don't believe everything GitHub claims about implementation
languages of projects!
So this is NOT the same as the "m11(1)" in 2BSD (which is written in
itself, i.e. MACRO-11)!
Once upon a time I wrote some first-year assignments in PDP-11 assembly
on a PDP-11/60 running 7th Edition, and we used a MACRO-11 assembler
with a manual I had bought for it that was clearly directly produced by
DEC (but I think I bought it at the university bookstore).
Would that DEC manual have been for the UCB m11(1) or a sibling, or was
the UCB (nee Harvard) M11 a reimplementation of the DEC RT-11 MACRO-11
assembler?
I wish I could find my printout of the main assembler project I did that
year -- it was a complete arithmetic expression parser (with nested
parenthesis support) for an integer calculator that I implemented based
on a nice flowchart I had found in a book at the time (the basic
assignment didn't require operator precedence or parenthesis support,
but with the flowchart I found it very easy to implement the whole
works). I probably accidentally recycled that box of paper though....

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.

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.

I have an extra special expanded version of Kirk's DVD. Some of which
I'm not allowed to share, but the brl stuff wasn't in the list.... Do
you have that stuff Warren, or should I send you a list and ask Kirk
what we can put up? He's here in ottawa at BSDcan with me at the
moment as luck would have it... Or do you have it all already and it's
been filtered...

Do you mean the version with the historic1 and historic2 directories, or
