Try as hard as I can, I can't find ANY relatively modern
computer that needs 6SN7s (a dual triode, octal base),
not even 12AU7s.

You didn't look very hard:

ERROR on "correction,"

Yes, *you* made an error, Len.

That's a 2002 ad-promo, four years OLD.

You wrote:

2002 is certainly "relatively modern" compared to 1946.

You made a mistake, Len.

A click on the link for more data turns up blank with
the small advisory of no suppliers for this item. :-)

You specified "relatively modern", not "current production".

2002 is "relatively modern" compared to 1946. And that system was
brand-new in 2002.

Search all you want of the HP, Dell, Compaq, the
independents such as PC Club...or the big warehouse
suppliers such as CDC or Frys. You won't find any
with vacuum tubes in them on the market this year
or the year before.

So what? You specified "relatively modern", not "current production".
2002 is "relatively modern" compared to 1946. And that system was
brand-new in 2002.

You cannot change the criteria after the fact.

So what? It's only been 60 years since ENIAC was announced...

Tsk. You've been around for a decade less and your
THINKING is obsolete and self-centered.

You mean, like someone who doesn't want the zoning in their
neighhborhood to change in any way at all? Who wants the standards of
the very early 1960s to be enshrined forever in his neighborhood?

Like someone who wants to stop development of land he does not own?

BTW, what did ENIAC have to do with AMATEUR RADIO?

That it was practical in its time.

What do your ramblings about non-amateur-radio subjects have to do with
amateur radio, Len?

Anything at all?

Oh yes. Many of those who worked on ENIAC were hams. You did not work
on ENIAC and have never been a ham....

ENIAC and the amateur code test deserve a place in
MUSEUMS, not the reality of life in today's world.

In your *opinion*.

Please direct any more hero worship of ENIAC to the
ACM historian.

Why deal with second handers when the real stuff is out there?

Did you finish reading the US Army historical monograph I linked to?

Here are the links again:

Electronic Computers Within the Ordnance Corps

Historical Monograph from 1961

Karl Kempf
Historical Officer
Aberdeen Proving Ground, MD
November 1961

Index:

Chap 2 on ENIAC:

http://ftp.arl.mil/~mike/comphist/61ordnance/chap2.html

Tree of Computing:

http://ftp.arl.mil/~mike/comphist/61ordnance/chap7.html

That's the real stuff, straight from the Army. Covers not only ENIAC
but its successors. Read what the US Army Historical Officer wrote in
the official US Army documents.

The "Tree of Computing" sums it up nicely.

btw, the "Ordnance Corps" are the nice folks who take care of things
like how to do artillery barrages....
