LOL
For the record, I'm a pretty huge DEC fanboy. I don't really use them for anything, but I have a couple of old bits of DEC hardware in my basement, in what I call my lab. Most folks don't remember DEC so I never get to bring up my DEC-love.
They helped sponsor my research and even provided me with enough kit to get my business going. The latter was scrounged from what they left me when I hit the pavement and the rest was comfortably financed.
So, I'm biased - but they did make some good stuff.
They let us down even more later and eventually we dumped DEC entirely.
I stuck with 'em until Compaq took over the reins and when we replaced hardware after that we bought a lot from Sun Microsystems.
When the building lost power, all of the workstations rebooted.
This is why you have battery and/or generator backup so that you can gracefully shut down the system. I'm not sure that the computers failed you any more than your managers failed you. Power redundancy was a thing even back then. If the power was out for x-amount of time, you executed a graceful shutdown. Then, if the mains power came back on within that window, you'd still wait for the Hz cycles to match the grid frequency.
I gotta imagine that it's easier for today's tech workers in many regards.
Ah well...
I should get a DEC logo tattoo.
They were just a ~45 minute drive from where I went to school at the time. Without them, I'd not be where I am today. Well, I might not be where I am today.
