I did a lot of Pascal programming on I think a CDC6300 (?) at the university. If you could get to a terminal you could submit a compile job and wait for the operator to hand out your printed output. The system was case-insensitive and some terminals were all uppercase (of course monochrome, I guess 80x24 or so). So even minor typos took like 20 minutes to be reported. I recently got curious about running a PC from floppies and found out I could get an external USB 3.5" floppy drive and boot a (I think) 2013 or so Thinkpad into DOS 3.3, with some doing. Managed to edit Lotus 1-2-3 with DEBUG.COM to remove copy protection. Of course much useful info to do this was on the web.

That was nostalgia also, but the old days with the terminals and line printer output were really something.
