There are many scammers taking advantage of online markets, but
for a organization that needs to repair an instrument or industrial
controller that runs on some DOS laptop with a proprietary
interface, those "jacked up" prices are much cheaper than the cost
of downtime or replacing the device that requires the old controller.

People who need to repair a controller don't have the luxury
of waiting until something shows up on ebay, but will deal directly
with the same vendor year after year.  That vendor will try to have
inventory by purchasing "in demand" models wherever they can be
found. and may also deal with spare parts for the instruments.

At my former work, old instruments generally get retired when
the person responsible for the instrument retired.  New hires get an
equipment budget and can't be expected to master all the ins and outs
of keeping outdated gear going, but are familiar with current instruments
and software.

Many computer museums will collect several instances of a given model
until they are able to cobble together one that works.  They may save
parts they know they may need in the future, but the leftovers go to
scrapyards that specialize in technology artifacts and will provide
non-working gear to decorate movie sets, etc.. as well as selling any
parts that are in demand.

Thanks, Samuel and George. By removing the file

~/.local/share/mime/mime.cache

as suggested in the mentioned comment, the problem was fixed!
