If you code in pen and ink before even going near the computer, that
counts.
Back when I were a lad, we didn't use no debugger. We'd print the
code,
and attack the printout with pencils out to mark all the bugs and
corrections, then type the changes back in.
Tim, waiting for one of the old codgers to tell us a tale of how they
had to make the valves and warm them up before starting... ;-)

Type them in? I remember punching them in on Hollerith cards.
Dropped a pile of them once.
That motivated me to have the punch card machine to put sequence numbers
on the cards so that they could be resorted again.

Try dropping two trays , each about 2.5 feet long. They did that to me
in the data center when I was in grad school. Luckily I had just
printed they contents out and resequenced them. The manager of the data
center had a cow when I told the staff to put the deck back together,
but my advisor (bless him) stood behind me and insisted that if they had
taken due care it wouldn't have happened.
Ah cards, loved 'em (not). And drum cards. Boy there was an arcane art!
