There is plenty of documentation on the pdp11 45/70. Start with the
handbooks:<br>

<br>
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:<br>

Dep is for "depositing" values into the simulator's PDP memory
space.<br>

<div><font face="Arial" size="2"> 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?</font></div>
