Yes, non-existent. That's what I was suggesting. As I remember it, a lot happened between 1983 and 1991. I did not own a PC that could run UNIX in '83, but I did in 1991. Perhaps it was the same for Torvalds.
No, I don't think RMS's GNU was targetting "PC's", i.e., non-shared computers, in 1983. Few people would have owned them. My point, perhaps missed by others, was that Linux was aimed at a new bit of hardware that many people had acquired by 1991, the 386 PC.
