So for how long. At least unicorn has a '*' beside the TTL
that is no longer manufactured. That is a good chunk of
them.

Hi
 The time may come that these part become hard to get but
unless someone burns down places like Anchor and Unicorn,
they'll be there for some time.
 My point is that most of these are still available. The
fellow that needs
one can still buy the correct replacement.
 Since both companies sell NOS parts, one might even get a
good
date code.
 I expect that someday, the supply will run dry. There are a
few
parts that are already getting hard to find. 74S38 are one
of them.
 The ones that are really bad are the custom parts. The ROM
chip
for the KIM is a good example.
 I have a board that is waiting for a bus inteface chip. I
watch
but don't have a lot of hope.
