Please forgive my assumption and ignorance. What OS ran on the PDP-8/i
or PDP-15/30?
I fully get falling back to old habits that work well, especially in a
constrained environment.

Doing different things based on the (lack of) speed of the connection
makes complete sense.

In light of the (lack of) speed aspect above, that seems perfectly
reasonable.
I too do something similar in vi(m) as far as confirming some changes as
I gain trust that they are doing the proper thing.

ACK

Fair.
Will you please elaborate on what you mean by "editor scripts"? That's
a term that I'm not familiar with. — I didn't see an answer to this
question, so I'm asking again.
