> With open source projects (and in particular ones like Linux where there's a huge number of contributors and interested parties), support for would-be niche facilities can keep going as long as there's someone with the knowledge and spare time to do it.
And that increasingly gets difficult to do. i386 support went down the drain in the kernel in 2012, i486 is probably going down the drain as well this year [1] and soon-ish another bunch of really really old stuff will go as well because it isn't maintained [2] - good luck finding someone still running IPX networks or ISDN hardware.
