Well doesn't this really come from how Apple started? A gradual progression of two guys in a garage,
first the Apple I, then the Apple ][.
So as they were building their machines I guess
they decided, (or the need arised) , we need large
capacity of storage as the tape player was too
slow to load files. Hence the disk ][ was created.
You want extra accessories, make a card for it.
So the memory, communication , printing was created.
So through learning through all of this, the first
os was introduced. Apple III SOS.
You can't blame theme or compare as they just
wanted to build computers and literally started
from scratch. It makes interesting history and
I find that by looking at how it was done then
(by reverse engineering) it shows just how
smart they were.
