Yeah, I remember coming in Wednesday morning, Jan 2, 1980, and having to drop my planned tasks to work on some programs that had failed in their last production run. Child Support collection programs with a 20-year planning function that suddenly went all funky.
So Y2K wasn’t really such short notice. It was just that the work to fix it kept getting put off by managers, who wanted you to spend your time programming the latest bell or whistle they wanted added to the system!
