Surenuff, Bob's a TRUE programmer.
I've done the above also, but with the less forgiving bipolar proms - you
can't erase your mistakes. <G>
I've also toggled the RIM loader into the PDP-8 I was in charge of so many
times that I had it memorized. Toggled the RIM loader into my PDP-11 too,
a few times after it was retired from supervising McMaster University's
linear accelerator into my loving hands. Unfortunately, the honeymoon ended.
It just took up TOO much space in my garage, and I couldn't think of anything
useful to do with it except donate it to a computer museum. :((
