We use to run Stratus VOS on Continuum series hardware at a lottery/poker machine company I worked at in the mid 2000's. It handled the jackpot system which decided which of 13,500 poker machines in our state would jackpot at any given time.
A reliable beast - never failed once in the entire time I worked there. Based on PA-RISC if I recall correctly.
Great story, thanks. I wish it said more about the architecture and also VOS.
Speaking of reliable beasts, I own(ed) a HP PA-RISC workstation that never crashed in six years, and it was even purchased refurbished (second hand, and educational rebate, and still the cost of a car in 1996 - but worth every penny).
I'd add "R.I.P. HP 9000 715/75" but of course she is STILL working now, twenty years later, and she is sitting right next to me (also got a second 715/100XC for spare parts in case on day they are needed).

That's not particularly surprising to be honest. If it's a server operating system, on hardware that doesn't change, there's not really a reason to update the OS unless there's a security problem found
It's not really a security strategy, but running an obscure proprietary operating system on a system which probably isn't connected to the internet means that you're only susceptible to highly targeted attacks by a dedicated foe.
Apparently the latest VOS release was in 2025, which means that somewhere there's a team of developers maintaining it. That's really the thing I find the most interesting, that there exists teams developing operating systems like VOS, strange DOS clones or UnixWare (perhaps less so these days). Must be a strange anonymous life.
