Come to think of it, there was very little that had more
than 2 layers before '80, so if that is where your supposed
experience comes from, suddenly it all starts to make sense.
DimBulb is certainly AlwaysWrong, but the above is simply bull****.
Perhaps in your little corner of the world you were still using
phenolic substrates too but others had moved on long before. We were
using upwards of a hundred layers (96, IIRC)
Hundred layers?
Just under, yes. Late '70s, yes.

We must have a language difference, because that is not even
close to true in english.
I can't help it if you can't comprehend simple English.

In fact, I challenge you to find any 100 layer boards,
anywhere, ever... within the next 30 years or more.
That statement simply shows the world your lack of experience.

Then quit posturing and show us!

Sorry, I don't have documentation from thirty years ago, nor would
I have the hardware to display it.

Granted, there's not one second I buy this, but let's see
what you come up with.

Of course you don't. You want to live in your little protected
world forever. The bigger world is scary, for those with such a
limited mind.

At the risk of damping down this lovely flame war, here's a 2004 article
on the IBM z990 series machines that discusses the module and board
layer buildups in detail:

The net: 110 layers in the modules and 30 in the cards.
