Sorry, but "bootstrapping a PDP-11 with toggles" sounds like
something too unsavory for a family list like this one.
*FAMILY* list? Holy crap! Then I'm glad I haven't stumbled onto
the Adult PDML list.

Cripes! You guys sure missed out on the "sexual revolution" didn't you?
P.S. We only had to do this every once in a while when the mainframes
crashed. We used the PDP-11 to set up the environment that booted the
IBM-360s (6 of them) to run. Later on in the early 80s we switched to
IBM 3090s which could boot themselves from 9" tape.
And Larry.... I knew how to do the procedure, but never actually
programmed a line to make it happen. I was capable of making running
changes to the code that the mainframes were running. But that was
just a matter of finding an address and rem'ing out a line or three
and carefully typing in the replacement code from the greenbar the
programmers gave us every night.
I just did that for fun, actually. I worked in the darkroom processing
1250' rolls of 9" (later 5") film in custom built Kodak (no model
numbers) high speed (100 ft per min)(1974 remember) high viscosity
(snot at 95-105 degree) chemicals. The machines were 60 feet long, 14
feet tall. Loud (mostly the dryer cabinet and hundreds of rollers). An
extremely competant operator (me) could start, run, splice on the
trailer, remove the processed film and shut it down alone. Barely.
