I think you have missed the point that old machines work well with old programs, why on earth would anyone want to spend money updating machine/computer and software to do exactly the same operations…

Well nobody would, provided nothing changed and those old computers and old programs were reliable. Unfortunately, they're not, which is why Martin suggests buying two or three for spares and picking the vintage with a certain amount of common sense.
My career in IT has been one of persistently finding that the computers available today aren't man enough for the work available. When I started, chaps would spend ages working to make a program small enough to fit on a tiny machine, and then even more time fine tuning it for the required throughput. As Robert mentioned, it's still going on. Trouble is computer programmers are expensive so – where possible – it pays to do away with a few of them by buying bigger computers that don't need experts to shoehorn programs into it.
Many other examples. Not good when the weekend accounting reconciliation is still chugging away on Monday evening. Not good when paying customers are timed out because a web server is overloaded. Not good when weather forecasts are inaccurate because there isn't enough capacity to crunch all the numbers. Costly when a corporate is beaten to the draw on the stock exchange because their computer is a few milliseconds slower than the competition. Failure of a computer system to keep up with real events is catastrophic to any automated process control system, and fatal to military men.
Very few customers want exactly the same operations. Once a simple Word Processor was enough, then people needed Spreadsheets, and small databases. Then collaborative software for team working – email, messaging, IP-telephony, video-conferencing, Powerpoint. CAD/CAM, 3D printing, data mining, process control and CGI. Digital cameras and Games. The Internet, Cryptography, Virtualisation, E-commerce, Search Engines, Smart Phones, Face and pattern recognition, the Entertainment Industry, Robotics and Cyber Warfare. At the moment there is no end in sight.
Having a valid reason for wanting old programs on old computers is the exception that proves the rule. But it's a niche requirement. Most of time most of the world needs more powerful computers and faster communications.
