Well, I got the ones I needed (I got 2, one for me and one for the person I was configuring a Mini-PC for) from China with Aliexpress, and in my experience you can usually find adapters for old tech directly from China even when stores in the West don’t have those.
In fact I was curious when I was writting this comment and I checked and it turns out they also have Floopy Disk USB adapters and, funnilly enough, they costs the same as the USB DVD Reader/Writters (which makes some sense as eventually the whole functionality is integrated and the cost is mainly the mechanical parts and assembly, plus those things are probably small manufacturing runs).
Most electronics factories over there aren’t exactly designing top of the range modern consumer electronics, but they’re perfectly capable of designing even complex electronics products (in my experience, they have more trouble with software than hardware) - hence for example there are several Single Board Computer designers over there - and they’re so many that they’re constantly coming out with quirky products while competing with each other (and not all of which is stuff with lots of LED lights and which play some crappy jingles), so I guess it makes sense somebody over there would’ve created adapters for old storage media (in fact I was curious again, so I looked for and indeed found a “Vinyl player with USB recording”).
As long as Electronics in China keeps having the sort of competitive environment and lots of little factories like it was in the West before the 80s, I reckon somebody over there will keep on coming up with adaptors for old storage tech.
It looks a lot like in a way History is repeating itself: the Democrat Establishment in the US (who are a hard neoliberals, not lefties) fielded directly and without a Primary a guy like Biden who is less than in his prime and even supports an ethno-Fascist regime commiting Genocide (and, more importantly, is unwilling to walk back on that support even to improve his odds of winning against Trump, which is what we are being told is the most important thing in the World) all of which is making it far more likely that the Fascists will get power.
There are vast contradictions between what we are being told is the danger of Trump getting elected and the DNC and Biden persistently making choices that increase the chances of Trump getting elected and not walking back on those.
Surelly if “Stop Trump” is the most important thing in the World for them, the Democrat Establishment too would be walking towards the wishes of the electorate not just trying to push the electorate to do all the walking towards the wishes of the Democrat Establishment.
