The Mac-clones came during the early PPC-days, the only 68k-clones I'm aware of would be things like Emplant or Shapeshifter
No doubt this
macintosh clones are a figment of my imagination :-o Some mac clones no doubt could be upgraded to PowerPC just like the amiga, but that does not mean the mac clones made their appearence at the time the PPC macs made their debut.
What has the abilty to run another OS has to do with the question wether Kickstart is an OS or an BIOS ??
You do not need Windows (or other operative system) to run linux, beos, aros, etc. only the bios of the machine.
You know, one could start linux from Workbench (thats how I did it when I tried 68k-linux for the only time).
Nowadays you may use tools like vmware, qemu, etc. to run another one operative system inside another, but that does not change the fact that operative systems are created to run atop of one bios (be it phoenix, open firmware, efi, linux bios, etc.)
Exec, Intuition,GFX and DOS are in ROM, and even started before anything is loaded from disk
You may place parts of an operative system within the bios, heck linuxbios includes the whole kernel, kickstart 3 has fonts for crying out loud. But that does not change the fact that the bios is the "basical input output system".
Oh, and that book was written years after Kernie&Ritchie developed and documented C
Are you trying to imply that the "Amiga Hardware Reference Manual Third Edition 1991" was written before the amiga made it's debut in 1985? holy time continium distortions batman :-o
or that Kernie&Ritchie should sue all C programmers :-?
