>BUT. I worked at a place that used IBM 360s...Then one day an engineer brought in an Apple II from home and ran the programs on that.
The 360 was introduced in 1964. The 370 was introduced in 1970. The 3033 was introduced in 1977. The Apple 2 was introduced in 1977. So, yeah, if you were still using 360s contemporary with an Apple 2, no wonder the engineers were frustrated.
Lots of organizations run those computers for very long times. It was not unusual for a medium-sized company, a factory or some local government to be running 10 to 15 years hardware.
