Before I came to ISU I used a DecWriter at Wazzu that was hardwired to the campus mainframe, two buildings over. Reams and reams (and reams) of wide green/white tractor feed paper. I probably killed a thousand trees a month with all that paper.
I also worked in an accounting function in SF where the data entry operators were in a clean room, and the computer took up two more rooms and used tapes.
Then again, I'm still trying to figure out my smart phone that is apparently smarter than I am. I only gave up my clamshell last spring.
Some of us old fogies do try!
Onward and upward!! DEC is one of my all time favorite companies. Green and white tractor paper and tapes, that sure brings back memories!
