I believe the term "workstation" came from the integrated interactive engineering design terminals/systems.  Can't remember details, but companies like ComputerVision had had them before UNIX and 68000 were a thing,

It seems like there are bountiful articles able the decline and fall of the UNIX workstation, but I’ve had a hard time finding narrative about workstations prior to the Stanford SUN workstation.

* was the SUN-1 the first commercially successful product? What are the “it depends” edge cases?
* were there common recipes for proto-workstations within academic or industrial research? What did those look like, who was involved?
* What do I really mean by workstation? Ex.gr. If an installation had a PDP-11 with a single terminal and operator, is it not a workstation? Is it the integration of display into the system that differentiates?
