These are two totally different worlds! The only way you could get FreeDOS

virtual machine. Again, FreeDOS can NEVER run natively on a RPi...
With DOS it would mean too much work - but I believe a group of determined
coders could be able to port, say, CP/M. Of course it would be "CP/M-like"
OS for RPi rather than "strict port"
Well, there used to be CP/M 68K (running on the Motorola 680x0 family of
CPUs) and I think there was a Zilog Z8000 port as well (not to mention
the original port from 8080/8085/Z80 to x86), but I honestly have never
bothered how that was accomplished. Beside a bit of "looking around", I
have never really used CP/M-86, though I did used CP/M-80 extensively
before the IBM-PC (and similar ones) came out...
Why would they do that? To create much simpler OS for RPI than Linux. Who
needs that whole complexity on such little SBC? CP/M would do just fine.
Well, there is always RiscOS... :P
As Chuck Moore (Forth creator) once said: "most computer operating systems
devolving to caveman interfaces ("point at the pretty pictures and grunt")"
Now comparing Forth to other OS is a bit of heresy... LOL
