Bill,
There is plenty of documentation on the pdp11 45/70. Start with the
handbooks:
http://bitsavers.trailing-edge.com/pdf/dec/pdp11/handbooks/
As for programming in assembly, most of the documentation is for DEC
OS's. However, the manuals for Unix v6 and v7 had assembly sections.
They are available here:
Assembler Reference Manual from Sixth Edition Manual (postscript):
http://wwwlehre.dhbw-stuttgart.de/~helbig/os/v6/doc/as.ps
Section Assembler Reference Manual in Vol 2b of V7 Manual (pdf):
http://web.cuzuco.com/~cuzuco/v7/v7vol2b.pdf
Dep is for "depositing" values into the simulator's PDP memory space.

When Ken Thompson coded UNIX it was in assembly. The first
versions anyway before B/NB/C. Is there in existance pdp11 (45 or 70
?) intterupt (vector) lists or IRQs and so, registers that shows how
to code in assembly on a pdp11? I am sure simh does it. Isn't what the
"dep" command is for?
