What I mean by it was on life support in 1978, is that already Kodachrome was starting to lose market share to other film technologies, like E6 and C41, even if digital had never been invented, we would still have seen Kodachrome fade into history.

On the market share issue, I have no disagreement with you.

I did, however still prefer the qualities of Kodachrome right through the early 1980s. When the Kodak lab in western Canada closed, that definitely started to wain.

I assume that you weren't in Canada at the end of the 1970s, or bought Kodachrome from outside the country, because as far as I am aware all Canadian sold Kodachrome included processing until the early 1980s.
