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.
