A lot of old standards are still in use in industry. Our IT hardware team had a horrible job recently in trying to track down a PC that would run Win10 and also still had an ISA slot for one of the cutting machines in the factory. Either the old machine was no longer up to the job or it had died. Air-gapping wasn't an option in this particular case.
Of course, it didn't help that they were trying to find something from the company's current stock of machines that might do the job, rather than just drop a few hundred on a new motherboard for the controller of a cutting machine that is worth tens or hundreds of thousands, but I digress.
