Being a dumb person, I am gradually replacing all of my software (outside Windows :-)) by older software because I like the speed, efficiency and weirdness of code produced for machines which have been mostly extinct for decades now.

As I feel surprisingly comfortable with most of the replacements (the latest one being TECO, replacing ed (please don't judge me)), I wonder if it would be worth a dare to limit yourself to software available before 1985* for a week. I am fine with allowing web browsers though... ;-)

Anyone in?
