[Simh] pdp11 and unix

[Bill Cunningham]

    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?
