Hmm, what I am going to tell now it's all the pure truth. although I know some people will not believe..
My A600HD had a 1.3 Kickstart and no HD or IDE Interface.
You see, my dad bought this computer to me, and the only thing I knew about amiga at that time was how to boot a game and play it . (Not much different from today
) . The "hand holding the WB disk" in the startup of my A600 was the same of my father's A500 , so I saw no problem on it.
Only years laters I learned about all those stuff like Kickstarts, Fat Agnus, etc etc etc , then I asked my dad why my A600 had a 1.3 rom and no HD, and he just answered "I don't know"
