The lore is that the world was moving to 3.5 and Alan Sugar (who owned Spectrum brand later after Amstrad bought them out) got a huge job lot of drives and disks cheap so they used them for the +3 as well as the existing CPC systems that had them (in fact the +3 used a modified version of AMDOS which ran the drives on the CPC).
It wasn't a terrible spectrum but it was already very obsolete by the time it was released.
It had a much better BASIC, and CP/M was also available (CP/M Plus).
Between the Amstrad PC1512 at the school club, the other friends lucky enough to have Amiga 500 which organized demoscene like parties at their places, until I finally got hold of a 386SX.
I'm not sure what else was there that they'll find interesting. Maybe they'll let me know.
I worked in a Mac lab briefly in college and we ran Disinfectant from time to time on the lab machines. Sometimes we would find Mac viruses infecting a file or two and I collected a few of these on a floppy. The archivist seemed delighted to have a few disks with "contained" Mac viruses as well.
When I used floppy disks routinely, their lifespan was a matter of months if they were used regularly. For stuff I was working on daily, I would always save it twice to separate disks. I'd be fortunate to get through a school term without having disk errors, so I learned pretty quickly the value of having multiple copies.
For stuff that was just archives, saved and then rarely accessed, they would survive longer. My guess is just that the read/write heads were fairly abrasive and wore down the magnetic layer of the disks pretty quickly under heavy use.
We really need something that could store data for 80 years minimum. Which is really just a life time of a person. Stored well and right paper could out last all of our digital alternatives. The M-DISC is expensive per GB, and I think they went bankrupt in 2020, and BlueRay disc is too small in capacity.
At this rate of things we may never own anything physical again.
The issue is that anything you made like that would need to be forward readable because storage capacity demands only ever increase over time.
i.e. imagine a 1.44MB 80 year floppy disk from 1985, while it'd last til 2065 no one would use it in 2025 because you'd need about a thousand of them to hold a modern 4K video
Minidisc. I have discs that are 30+ years old that have been abused their entire life and still work fine with no noticeable degradation. I specifically choose this format to archive audio because the disc housing works great for environmental protection and I’d eventually like to give my music collection to my children/grand children. The discs can also store data. My minidisc player shows up as removable storage device when I plug it into my computer so I can throw anywhere from about 140mb-1Gb(hi-MD) per disk.
Officially they’re rated to about 50 years, but if you sealed them and stored them properly then they could easily make it past 80 years.
An enterprising individual could probably clone an old device and flash a stock firmware to it if they really wanted to. The functionality that goes first in older devices is usually the write head, but you’d probably still be able to read discs for decades if you took care of the device and stored it well.
The minidisc community online is also very active and people are active working to reverse engineer virtually every aspect of the players and disc writing software, and some people even produce new drop-in replacement parts for the components that tend to fail like OLED displays, etc.
Anecdotally, the stuff my grandpa filmed on Super-8 is still in nearly perfect condition 65 years later. But most of his 16mm stuff from just a few years earlier than that has vinegar syndrome, so it's not "just film it and you're good"
If the film is rare, highly flammable, and was made before 1951, there's a good chance it'll end up on George Willeman's desk. Or more specifically, in one of his vaults. As the Nitrate Film Vault Manager at The Library of Congress' Packard Campus for Audio-Visual Conservation, Willeman presides over more than 160,000 reels of combustible cinematic treasure, from the original camera negatives of 1903's The Great Train Robbery to the early holdings of big studios like Columbia, Warner Bros, and Universal. And more barrels keep showing up every week.

There was a great talk by Jason Scott (textiles) on how he dug out Jordan Mechners original prince of persia source code from the sands of time.
I see what you did there

Both should work on macOS/Linux/WSL.
Good heavens this makes me feel ancient. Do today's BBC readers really not know that there were two main sizes of floppy disk?
