Well, I wasn't the one using it, but in late 1998, I was working at a printer -- a big industrial one, with huge lithographic presses. The prepress department there was transitioning to using Macintosh G3s for DTP work, and I was there to help with that. The reason for the transition was that their old DTP needs had been served by some sort of DEC minicomputer.
It was about the size of a fridge, with dual 8" floppy drives, so I'm hoping it was a MicroVAX, but I don't recall. Each workstation wired into it had a VTerm, as well as a Barco graphics monitor and a mouse. You'd type in commands to their DTP software on the VTerm, then view the work as a line drawing on the Barco (all it was capable of -- photos had to be pasted in by hand) and adjust it with the mouse.
They'd been using the thing since the early 80s, but apparently it was breaking down and they were having trouble pulling people out of retirement to fix it, and that, plus the new digital press they were building, forced the transition to Macs.
The company got bought some years later, but is still in operation, so I guess things more or less worked out.
