I've got probably a lot more questions, if that's okay. How was the programming cycle in details? Say you wrote Fortran back then. (What were you writing?) You'd write Fortran maybe on paper. You think you have you program right. Now what? Was there a compiler to help? You had no video to echo back what you were working on?
