alt Hacker NewsThose operating systems already exist. You can run NetBSD on pretty much anything (it currently supports machines with a Motorola 68k CPU for example). Granted many of those machines still have an MMU iirc but everything is still simple enough to be comprehend by a single person with some knowledge in systems programming.

FWIW, Linux is not the only OS looking into dropping 32bit.
FreeBSD is dumping 32 bit:

OpenBSD has this quote:
>...most i386 hardware, only easy and critical security fixes are backported to i386
I tend to think that means 32bit on at least x86 days are numbered.

I think DragonflyBSD never supported 32bit
For 32bit, I guess NetBSD may eventually be the only game in town.
NetBSD doesn't support any devices without an mmu.
I think people here are misunderstanding just how "weird" and hacky trying to run an OS like linux on those devices really is.
