Further proof of my dinosaur credentials. That same year of Fortran IV, Engineering students had to have a sliderule. My brand new latest greatest HP-400 calculator with 9, count em, 9 memories, was not allowed for tests and exams. The memories were an unfair advantage because evil people could store constants and bringing notes to tests was a no-no.
Two years later, scientific calculators were required and slide rules were out. I learned then about the suffering of a pioneer. Probably saved a lot of Phillipine Mahogeny trees from an early death.
