Pretty much - I started work before even internal email was a thing, so everything was done on paper. And often hand-written paper at that. Hell, I made the first Word template for a work-item ticket! Before that we had custom forms to fill out.

Even better, the developers worked in a different building to our users, so there would often be a couple of days lag to getting a response. If you needed a quicker answer, you had to phone them, or schedule a meeting if you needed to explain something in more detail.
