But can your calculator run Linux?

I still have my HP50 but there's just no reason to use it. Anywhere I go I either have my phone or a computer. When I was in the air force I would have to go into EMSEC zones where you couldn't bring external devices, such as SCIFs, but the number of people with needs to be running engineering calculations in such an environment rounds down to 0. Certainly I wasn't one of them.
Even "in the field" nowadays, you're likely to have satellite connectivity and a laptop. There's just not really a use case for graphing calculators that I can think of. It's too bad, because they're awesome.
so can a calculator.
(NetBSD used to have that slogan with regards to toasters. I have not followed it for several years, so I don't know which operating system dominates toasters nowadays.)
In response to the joke about BSD running on a toaster, some joker created and documented a "toaster running BSD" which was accomplished by bypassing the toaster circuits and adding a motherboard with CPU, memory, storage and I/O.
Now those all make for good jokes, but it does not mean that toaster hardware is POSIX-ready, any more than a Macintosh SE is suitable as an aquarium.
But let us never forget that the Video Toaster runs with Amiga or Windows!
