Ok, you got the easy one.  Now here's the harder version of the
question.  Write a PDP-11 assembly language program that will set ALL
of memory and all of the registers (except, possibly, for PC) to the
value ZERO.

I'll post an answer in a week or two if nobody gets it.

(Yes, there are at least two solutions to this.)
