Ah, interesting tidbit. I would imagine that it's available in places that
deal in batteries.

I can easily imagine TTL disappering, but I think the
TUPs and TUNs [1] (as
Elektor used to call them) will be availalbe.
[1] Transistor, Universal, PNP, Transistor Universal NPN. Basically,
generic trnasistors.
I've heard of them, I think it was on Tony van Roon's site, but have never
seen those referenced anywhere else.
Elektor used to publish circuits with trnasistors
labelled TUP and TUN (and
diodes labelled DUG (germanium) and DUS (silicon), along with quite long
lists of components that would work in all such positions.
Nice to know where that came from, I don't recall that bit being mentioned in
the original article I read but that wasn't any time recently.
A list such as that might be of some interest.
