I started my career in 1981 working for 3 years at a defense contractor. By 1985 I started my first company to develop and then sell a spreadsheet like application for the Mac called Trapeze.
So what was it like back then in the dark ages? Quite different than today in many ways; not so different in others. There was no internet, no Google, no StackOverflow. It was just you and your friends and your brain.
Warning, antique history!
Ah, the good old days.
