- Quite possibly you still used punch cards to enter your programs.
- Probably you had a degree in something other than computer science. Math, physics, electrical engineering, something like that.
- Probably you were the only one working on whatever application or system you worked on.
- Probably you didn't have any kind of internet or email access. If you needed help figuring out a problem, you went to books.
- Very likely you didn't have any kind of proper source control, automated testing, or bug tracking.
- Most likely you didn't have any software libraries to work with other than whatever came in your language core library.
(I learned to program in 1981, but I was only 9 years old at the time, so some of this is secondhand.)
