RISC OS Good news for Raspberry Pi owners (ha!): the RISC OS port is progressing along nicely. So much so, in fact, that a Raspberry Pi-based RISC OS machine is in the works. Stable beta release of RISC OS for the Pi planned for September!

An OS still without memory protection (so, in a a way, without proper multitasking - it relies on good behaviour of applications) is a pinnacle of OS development for you?... O_o

I suppose the positive aspect of it is it forces you to write good code.

But what really happens, what mostly happened: code base becomes more and more unmaintainable, the attention is on trying to avoid nuking the OS while running - and progress grinds to a halt.

Nowadays, ~Amiga lives on, tries to remain useful, mostly on ports of PC software (just lagging in version, and in less stable state)

@Zima

Seriously dude ;) Get out of the 90's. That's when they introduced "Enforcer" .. which if you have a CPU with an mmu eg.. 020+68851 or a non-EC anything later enables mmu protection.

Yes, you can run without memory protection. No I don't think it's wise and don't. Yes, I do think that AmigaOS, VMS and OS/400 are the pinnacle of OS dev ;)

Seriously dude, those are just best effort kludges (and didn't make much difference in practice) - Amiga OS still doesn't have memory protection in any rigorous sense of the term.

Snap out of nostalgia, that's what killed Amiga, what keeps hammering nails into its coffin for almost 2 decades already... (BTW, NT can be seen as quite worthy successor to VMS, on technical level - how market realities forced NT into dubious ~userland practices is another issue; at least perceiving VMS or OS/400 as pinnacle has some merit ...but that's not what you initially claimed)
