It's much more common to find businesses running on very old hardware in developed countries, not in developing ones. Developing nations basically didn't use computers 20-30 years ago, there's no random remnants from that era beyond some extreme tail end. And, given how the PC & server market evolved in the 2000s and 2010s, it was cheaper to buy a then-current x86 than to import some ancient Alpha system from wherever. Especially so since software licenses didn't really exist in those days in developing countries - even government institutions often ran pirated software without a second thought.
