has found heaps of stuff, including a trojan dialer. so far it's listed 202 'infections' and still running. what
gives??!! why is it finding stuff and the others didn't?!


I am starting to believe that so called anti-virus companies may not only be writing viruses to keep themselves in
business, they may also be selling their customer data bases.

my findings with Norton last year. Never resolved. I simply gave up and moved on.

Actually Felix the fucktard, we do know why a digital cable is blessed

you are in fact the lawful prey of the spivs that sell such shit. By
all means give them all your money at least you can't then spend it on

I'd still like to see a double blind trial on that.

speaker cables can affect the sound from the speakers just as AV
interconnects do

well don't tell noddy. according to him Clocky is the cable expert
and I
know nothing about them :)




Nobody, including me, has ever claimed that I'm a cable expert.

just exaggerating for impact. but you were trying to tell me about
cables saying I didn't know what I was talking about,

You don't.

saying so doesn't make it true and never will. you didn't even know
quality HDMI cables had triple or quad shielding, so STFU!


And none of that makes any difference whatsoever to what you see on
the screen as you described.


yes it does, and the fact that you don't know why is just further
evidence of your ignorance regarding cables

Nor does it make a difference if the same spec cable has extra
shielding or not. It either complies with the spec or it doesn't.





and noddy did say he would take your word over mine, so don't get so
uppity

SEC means it had a security bit. If set, it would self erase before you could re-program it. Not a problem if you wrote the code.

You could also configure one of the mode pins so it would erase at power up, ready to be re-programmed. One of my first designs had a dip switch connected to the mode pin in question. I put a dab of hot glue on the switch after programming, to prevent the customer from accidentally bricking his unit. Of course, they could always be sent in for re-programming.

Did you ever get a copy of the BWD 530 manual, I would also like a copy.

It would be cheaper and much better to buy a modern digital CRO, eg
something like a Rigol 1052. Far and away superior than wrestling with
ancient junk.

I note you are replying to an email now 15 years old. Doubt if the OP
is still interested.

Old 'scopes are fine if they suit the job.

The only links that I know of for BWD manuals are here:
http://bee.mif.pg.gda.pl/ciasteczkowypotwor/B.W.D/
http://www.kevinchant.com/bwd.html

Neither has a manual for the BWD 530.

** Popular models like the 539a, 509, 821 and 824 are there.

My main scope is an 821 - like the one in this pic:

http://www.vinylengine.com/turntable_forum/gallery/image.php?album_id=1065&image_id=32914&view=no_count

Dual trace, 50Mhz, 6.3kV acceleration on the tube which has an internal graticule. Bought new in 1995 and in daily use since. So far, one 22kohm resistor and a switch pot have needed replacing.

BWD scopes are models of economical design using readily available parts.

I also have a Rigol DS1052E, barely used except for image captures for publication on the net.

**Dump the 1052 and buy a 1054Z. You won't be sorry and you'll likely do
what I did: Put the analogue 'scope on a shelf and leave it there. The
1054Z is a HUGE improvement over the 1052E. MUCH faster and more
responsive, more features, bigger screen and a far superior trace. The
probes are utter crap though. I can't part with my Tektronix 2232
though. It has it's charm. I'll probably keep it forever. I am still on
the lookout for a cheap 7000 series Tek mainframe, because I have a 7A22
plug-in that I can put to good use:

** Yes - operating is very easy and intuitive and the trace is quite sharp and bright. Being analogue means what you see is always real.

The same cannot be said for DSOs like the Rigol.

Learning to use one is quite tedious and you can never really trust what you are seeing - the fact that sampling is at a *different rate* with each step of the horizontal means the usable bandwidth is constantly changing and there are strange artifacts from aliasing too.

What you see in never in real time, there is always a delay and even when the input signal stops, the DSO continues to display it for over a second.

dim with higher horizontal settings. Doesn't happen with a DSO.

**That much is true. Vertical resolution seems to be still quite poor on
even high end DSOs. Analogue 'scopes rule here.

**I just checked my 1054Z. I don't have the time or the facilities to
measure it, but I'd estimate way less than 100msec for both. The delay
is not noticeable.

Like I said: The 1054Z is a MASSIVE improvement over the 1052E.

*** Yes, there is sometimes hundreds of times more information in a good scope trace than a grainy DSO screen - which always looks like noise to me.

** But it is long enough to completely miss contact noise when you operate a signal switch while rotating a good pot produces visible noise all the time.

I find the DS1025E near unusable for trouble shooting work.
