I just remembered that I download from the net the circuit diagrams of a
Honeywell H316 which was made using TTL (and ferrite core memory) :-D

Technically not. But their legacy lives on.

I do sometimes watch that, yes. Although it's not especially easy
figuring out when it's actually on TV. But if somebody else discovers
that it's on, I'll sometimes sit and watch it.
I think meeting Mr Fry might possibly be almost as interesting as
meeting Einstein. ;-)

You could live in a dark hole under a rock somewhere and you'd still
know who Einstein is. ;-)

Oh I am *so* not pronouncing that! :-P
I would also suggest that he is famous only to computer experts.

What the heck did you search for?! It's kind of a rather specific
question...

Well it would be more valid than a straw poll of *one* wouldn't it? :-P
Still, I guess this is going to be one of those things where no matter
how much evidence I produce that nobody has heard of these people,
everybody will continue to assert that my statistics are just wrong...

Quite a few of the names look hard to pronounce, but we'll see...

You can use the scientific method to prove that if you pour liquid from
one vessel into another the amount stays the same. Few people would call
you a scientist if that is the best you accomplished. So, that is why I
said that it depends.

I am afraid so. Though he could (and possibly should) have been a
celebrity for the common man also.

5 amps per PCB. If IIRC TTL uses 250 ma per chip and there were 20 chips
per PCB and 6 PCBs. Include the losses in the PS and it was just less
than a Kw. It glowed <joke>

I searched for "newton apple myth". First hit took me to a page that
linked to this.

I don't think statistically it would be. A sample size that's too small
is too small. Still, you might give it a go anyways, if anything it'll
get you talking to people in meatspace. ;-)

That's because you don't *have* statistics. You have a guess. You say
"nobody", but to prove that, you have to prove that *everybody* hasn't
heard of them. That's pretty easy to disprove.

Such as? In the list of names I provided, I fail to see how any except
Cerf's name would be difficult to identify the pronunciation from - since
they sound exactly the way they're spelled (and for that matter, Cerf is
as well, though you have to know the C sound is soft rather than hard).
