Before I started using Mac computers with fonts we used to use typesetting services to generate type for layouts. I believe the systems were called phototypesetting. I watched a few times in and around 1979-1980. There appeared to be a computer style keyboard & monitor, a device that looked like a computer and a big image setter. And, paper tapes taped to the walls. I assumed that was their version of a floppy disk.
Did those systems use fonts like we use now? Were they digital files? Who designed those fonts and what kind of equipment did they use?
