[Coco] DECB -> Pi2/3

Ah... yes. Even back when I was using OS-9 II, '89-'92 time-frame , I was aware of both OS-9000, written in C (primarily for the 32bit PC's...) and also OS-9/68k for the 68000 and greater CPU's -- which I think, at the time was still in 68k Assembler? (not sure about that -- but I seem to remember reading that?)

But they were back then and *still* are to this day, actual commercial for sale products, right?  So not exactly hobby level stuff, not to mention open source like NitrOS9 is.

You know about OS9000, right?  It was an OS9 derivative from Microware
that was written in C and compiled to run on 80x86, Power PC, and 68000
platforms.  There's probably no reason that it couldn't also be made to
work on an ARM machine too.  I wrote some software back in the 90s that
ran under OS9000 on an 80486 but it was compiled C code, not directly
written in assembler.  I still have the install disks for OS9000 but I
don't know if they're good.

> I’ve thought about this too.  Not sure this is exactly what you’re referring to, but it would be quite neat to see NitrOS9 ported to native ARM machine code on the Pi.  No 64k restriction – full address space / running at full speed using multiple cores … very, very lean.  Very quick boot. No Linux bloat. <- not that I am dissing Linux, however!!! :)
