alt Hacker News6 years is really not a long time at all. You can probably find heaps of open source software out there that compiles and runs perfectly on 20 year old PCs. It's not like the maintainer has to do much to retain support--they just have to not make the software dependent on new operating systems.
Bits don't rot.
How many of those 20 year old projects had to go through an architecture change that the manufacturer no longs supports? Come on man be reasonable.
