Nothing says a PDP-11 has to be in a rack with peripherals right? If one could devise up emulated peripherals that plug into the backplane or otherwise tear them down to fit in much less space, a PDP-11 could probably be made to inhabit similar desk real-estate as a workstation, especially some of the smaller LSI models. There's also the MicroVAXen but the SUN-1 beats those to the market.

All in all, I would wager workstation has never been a well regulated term and, especially once PCs and other micros got better, the delineation between a workstation and a consumer PC has just gotten blurrier and blurrier. For instance, I would use the term workstation to apply to my Raspberry Pi, someone else would probably chuckle at the thought while sitting at their modern POWER9 system. It fits all the needs of my non-day-job computing, so workstation enough for me.

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?
