Yes, I used my first computer in 1968 using punch cards for a CDC 6400 mainframe and then in grad school with 10 baud teletypes using search, replace and list line editors. When we upgraded to 30 baud teletypes we thought things we flying off the pages. By the time I finished my PhD in 1978, we were using full screen editors and the teletypes were being sold for scrap metal (and my lifetime supply of 6-40 hardware). Fast forward to today and we are doing everything in Java and moving to HTML5 and its looking more like back to the future for me.
