Plenty of us dinosaurs around. Work was not any less hectic. There were phones, beepers, inter-office mail, secretaries, and, of course, your boss would come to your office (or desk) and ask you to do something. You took your work home in a briefcase.
Some of us (mostly tech people) had email, crude chat, and internet before everyone else. The internet consisted of e-mail (outside your company even), gopher, ftp, telnet, usenet. Browsers did not come out until the early-mid 90's, but there was not a lot of content for a while.
I was able to dial into work and do work from home in the early 90's - using my home computer as a dumb terminal into my (or a shared) unix workstation. But that was for after hours, weekends, or when too sick to go into the office, but not sick enough to do nothing.
I had a few jobs before my life as a coder, but those were mostly labor jobs. I worked in "office maintenance" for a year or two while going to night school. I had a shared office. A shared phone. A shared van. My very own beeper. We moved offices (furniture and all), hung whiteboards, painted office, fixed desks, took files to storage, sometimes reconfigured office spaces - tearing down walls and putting up new ones.
That was still busy and hectic at times, but not in the same way you'd consider a job today hectic. I was busy getting tasks done, not busy being bombarded with tasks every few minutes.
