Hello World...


Arnoud van der Wel <A.P.vanderWel@...>
 

Hi Everyone,

Well, if we are introducing ourselves, let me have a go...

My name is Arnoud van der Wel, and I am situated in Enschede, the
Netherlands. My 'discovery' of old Tek scopes started with a 533A/1A4 that I
bought at a sale of surplus equipment at my university for about $25. Being
too big for most people, apparently, that makes it somewhat 'worthless'?

My collection grew steadily, and now I have lots of old scopes... a 515, a
545A and B, a 585, 531, 561, 564 and 564B, and of more recent vintage... a
7514 with a VERY interesting intermittent HT fault :) and a 7904.

I used my 533A daily and to my full satisfaction until about a month ago,
when someone gave (!) me a 7904 in working condition with a box of 7k
plugins, which is now the scope on my bench.. At least the 533A has a worthy
successor. :) The best feature of the new scope is actually the fact that it
is so quiet... :)

I also made a 'Tek scopes museum' website one rainy afternoon, which can
still be seen at margo.student.utwente.nl/~wel/tek.htm but which hasn't been
updated for (far) more than a year now. A site like that is a lot of fun to
make and lots of people come by with enthousiastic comments, interesting
anecdotes, parts, stories and pictures..

Not having any time for the website now, and not being likely to in the near
future, I am looking for someone who wants to take what's there and give it
the care and attention (and updates!) it deserves.. If there are any takers
out there who want a good start to their own 'Tek Museum' drop me an email
and we'll talk. You start off with (amongst others) a link from the official
Tek site to your museum, so you'll have no lack of hits. :)

Oh, and on the subject of responses to my site.... This morning someone
offered me a 511A by email. I really have no space for it, but we can't let
this be thrown away, can we? He has a .nasa.gov email so I take it he is
somewhere in the states...

So long,

Arnoud.

Unfortunately, these days, "small is beautiful"...

Gee, I remember when a 7904 would have been worth a *lot* of money. I guess
that makes me old, huh... :/ Hmmm, what's a 7514?

Ah, I remember repacking many, many fan motors.... <g>

I tried to access it, but my browser returned "unable to locate server". A
pity, as I'd like to have seen it.

Lucky devil... *Nobody* gives away Tek scopes around here... >sigh<.

Kind regards,

I just tried it and it is still there!

So the problem does not seem to be on my end of the line....

Hmmm... I double-checked the url (I'm having trouble with this mail program and
web addresses), so I wonder what the problem is? I'll try again today...

I just tried again, and same result. :(

By substituting "www" for "margo.student" and dropping the "/~wel/..." I was
able to get to the university, but was unable to get to your page that way. Is
the server name correct...?

Regards,
:)

The link works precisely as typed....

Can't do more for you than that, I'm afraid....

So long,

Arnoud.

Hiya. :)

Hmmm... vewwy stwange... might be my end, but I can't imagine why. I was able
to get into the uni server the "front" way, but when I clicked on *some* links,
I got the same message while attempting redirection to ancillary servers.

My guess is the university webmaster doesn't like Aussies...

(I used to be a university webmaster, and I know it's quite feasible to deny
service selectively this way, but I can't imagine why.)

Oh well...

Cheers,
:)

Hi Michael,

I may be all wet here but I think your server has to know about the URL you wish to
go to or it won't let you go there. Maybe your server just does not recognize the
web address you are trying to reach. As I understand it, when a new URL comes on
board, the owner has to let the world (internet) know about it so the various
servers of the world can recongnize and find it. The servers are constantly
updating their database of valid URL's and maybe the one you are looking for never
got into your server's database. If not, your server could not find it, but
others still could . . .

But I may be completely off base on this one. It makes sense to me . . .

Hiya Arnoud,

I'm not gonna give up... <g>

Can you supply me with the ip address of margo.student.utwente.nl ? (there's
more than one way to do almost anything... :)

Cheers,
:)
Michael

Hmmm... I'm not prepared to say you're wrong, but I'm not certain you're right
either. I just don't really know. Either way, it's a pity, as I'd like to see
the site. Oh well... Never mind.

Cheers,

Hi Michael,

margo.student.utwente.nl has the IP address 130.89.221.72

and if that works, then I probably know what went wrong: the IP address used
to be different, and maybe changes haven't filtered around to the other side
of the world yet..


Regards,

Arnoud.

Hi again all... :)

FOUND IT!!!

Thanks for that. Looks like it was a nameserver problem after all... Great
pages, but I take issue with your comment that the 453 "doesn't belong in the
list of the great tek scopes..." The 453 was my scope of choice as soon as I
could get my hands on it! And the first thing I did was throw away the mesh
filter and fit a blue one. Lovely! :)

In my mind, the 453 is the "classic portable" oscilloscope.

Cheers,
:)

Stan or Patricia Griffiths <w7ni@...>
 

I was there when the 453 was introduced to the world. No doubt about it . . . it
was revolutionary. You have to put it in the context of the other instruments
available on the market at the time. Nothing could touch it. IBM was certainly
in love with it . . .
