*** Microsoft even has a subdivision dedicated to maitaining compatibility, with an entire subsystem in the OS that effectively patches select programs at runtime so they can "fix" older software on customer demand. Raymond Chen, a member of that subdivision, has a lot to tell about what that feels like in his blog, [https://blogs.msdn.microsoft.com/oldnewthing The Old New Thing].

*** Considering that backwards compatibility is one of Microsoft's highest priorities, this just goes to show how difficult it is.

*** There's a semi-apocryphal story about an old industrial computer at a Russian plant whose power is backed by [[NoodleImplements several UPS batteries concocted by resident engineers]] - because if it ever turns off, it won't be able to boot again since the 8-inch floppies with the software have long since crumbled to dust. And that would render all the (similarly outdated and incompatible) equipment it controls useless.

** It's not just software and hardware that falls victim to this trope; it applies to physical materials too. Case in point, FOGBANK, which was an unbelievably-classified plastic used in Trident missile warheads. FOGBANK production ended in 1989. When the Navy wanted to refurbish its existing warheads, they had to build a brand-new factory to produce FOGBANK again -- and discovered that the documented procedures didn't work. It turns out FOGBANK relied on an ''impurity'' included in the original batch, and this delayed the refurbishment by nearly ten years.

** The biggest offender of this is, of course, the CPU and RAM. RAM sticks change layout every few years, as do CPU sockets. This seems to have become progressively faster since we hit the new 10s. For example, Socket 5 and Socket 7 are electronically compatible and you can actually upgrade a 486 to a Pentium while reusing the motherboard. Nowadays, upgrading the CPU will also mean replacing the motherboard. Same goes for RAM, the 72-pin slot was standard for a very long time, almost a decade. Nowadays, not so much. Chances are you may also need to upgrade to a newer RAM type when you get a new motherboard along with that new CPU.

** If a pre-Win2000 (especially DOS-based) game had Redbook audio, such as ''VideoGame/{{Descent}} II'', it often required an analog audio cable directly connected to the soundcard from the disc drive, as opposed to the digital playback of later Windows versions. Fortunately, the ''[=D2X=] Rebirth'' sourceport/frontend for ''Descent II'' allows the CD music to be played digitally, and ''VideoGame/{{Turok}} 2'' has a patch for the same purpose.

* While the PS3 can run PS2 games, it does it by software emulation, as the Cell processor is completely different from the chip set used by the PS2. There was some uproar when back in 2007, rumors abounded that certain future models of the PS3 would lose this software emulation function, which they did.

** Frustratingly, the European PS3's were made with a different hardware set, and don't have any real emulation function at all.
** And now, Sony will allow you to play PS2 games on any PS3, [[OneGameForThePriceOfTwo but you must buy the games from the UsefulNotes/PlayStationNetwork Store even if you already own the DVD]], and even then it's only titles they approve of, which is not many. Thankfully, you can play physical copies of [=PS1=] titles on any [=PS3=].
* And now, the latest announcement is, the UsefulNotes/PlayStation4 will not be able to run games for previous Playstation consoles at all offline, [[http://kotaku.com/5985785/sonys-cloud-gaming-could-bring-new-life-to-old-games however you can stream the system's backwards compatibility with PS1, PS2 & PS3 games to get around this]]. However, that still leaves you at the mercy of your Internet connection, and [[RegionCoding whether your region's GaiKai service has the games you want to play]].
