The "lousy 40 year old 741" is still in volume production with at least 5 major manufacturers. If it meets your needs, use it.

The last time I looked, parts of Columbia are modern.
The school kid is making a circuit with a 40 years old opamp so either he is in the 5th world or his text book is 30 years out of date, but I said it is fine in his simple circuit.

Many countries make electronic parts that are not available there.

here a mesage from the 5th world

741 has landed opto couplers expected nexts 4 months

but PIC's are still smugled into the country and the rumor is that it's still prohibitive to own a PIC although they wan't to losen up a bit because of improving the comercial compatitive ranking with other countrys

still only hardware will not do the trick but you can't say that loud unless you're a NGO

still than they don't provide schooling also so why telling it and watch it go wrong

i am busy in the mean, evil and hard comecial sector (from an NGO point of view)

but i know i make a change i do teach my coleuges things in a trade where there is not even an school for in this country

so if our company is sucsessfull in the comercial world (and it is) we are moving the standards up

back to topic

it's a pain to get some desent components here and it's sometimes realy a challenge to get something done but after all if you get it done the satisfaction is bigger

so before we start to burn a old solution/shematic down (that is already replaced by better ones long time ago)have a thougt about the situation a person is in , it might be the only thing he can make

I like talking about new high-tech parts, not old antique parts.
Maybe there is a website in a 5th world country for talking about old stuff.
