That's true, but there are decades worth of NOS
TTL chips on eBay. I've
gotten a bunch of them recently of the types I think I'll ever use. And
really cheap at that.
And after those decades worth are gone, a few more decades worth will turn
up with just a little looking. We will all be dead when the things become
unobtainium.
I am always getting into arguments with folks that are worried that the
1960s transistors used in early minicomputers (PDP-1s, Packard Bell 250,
and the like) are "all gone" or "extremely rare". 'Taint true,

all you have to do is look.
