Even then not every university or college had a computer; often you only had a terminal or remote job entry using cards and a printer to a larger computer some place.
Fast forward to today and not only can most people afford a computer (sometimes receiving a refurbished computer for free), but computers (and operating systems) are so powerful that you can solve almost any problem a computer is capable of solving, given enough time and memory.
Of course, most computer people are familiar with the Raspberry Pi (RPi) and its various "Pi-like" single-board computers (SBCs), which were first created in 2012, and the many types of projects that have been created with them: small servers, desktops, embedded devices, etc.
