Also a couple of other reasons.
1) In the US 386s with 30pin simms are available for free if you
know where to go (sysadmin's closet). A 386/40 with 8 meg is not
a had hacker's machine.
2) Old machines sometimes have "personalities" so we hate to replace
them. You have to be a hacker at heart for this one. I'm trying
to get a guy at work to sell me his Amiga so I can get
Linux running on it for no good reason. :)
