That is a long time ago! Were programmers as much in demand as they are today?? :D
You wrote more code to get less done with fewer people
You wore a collared shirt and maybe tie to work everyday. You were more likely male.
There was no remote
Computers required AC and you wore wool if not
You stored your work phsically. 9 track tape, paper tape, eight inch floppies, etc
No internet. No googling answes. When you had a bug you kept at it for days until the answer was found. If there proto pair programming this was it. Someone sitting next to you looking for the bug together.
Full screen editors?Symbolic debuggers?Static code analysis?IDE?
Were decades away.
