[Simh] load

[Clem Cole]

One other thought - it will likely take a little work, by years ago Jim
Reeds of UCB took the old Harvard Macro11 and Link11 tools from the
original 1977 USENIX distribution tape and hacked on them/updated them for
2BSD.   The important thing for you is he rewrote the linker into C (the
originals were in Macro11).   IIRC, his linker takes DEC PDP-11 *objs and
creates a.out.   You have to look at the sources for yourself, but that
might be a starting point for something like what you want.   For the
linker check out:
https://github.com/eunuchs/unix-archive/tree/master/PDP-11/Trees/2.11BSD/usr/src/new/l11
The assembler is called m11 is ../m11
