Thirty years on.

Those were better days. Can anyone imagine "Auntie" embarking on such an ambitious (not to mention useful) project today? frown

I got rid of all my BBC Micro (etc.) stuff about twenty months ago ... probably a mistake (yet another), but there you go.

Hacking infusion pumps and the like just hasn't held the same appeal, somehow. whistle

Meanwhile, here's a bit more (including a nice shot of the NewBrain). Notice those other "thirty years old" stories under "Related stories" as well.

Here's something which may be of interest to some folk:-

Disk Rot!

It's sad to think of so much classic software - especially home-grown one-off's - heading towards the bin. Stuff stored on data cassette tapes has faired just as badly (or worse) of course. frown

Luckily most of the good commercially produced stuff has already been saved as images and poked into various places around the 'net. And thankfully ROM-based stuff still marches on (and has been "imaged" as well)!

Well, here's a real classic (and working, too)!

They reckon it was very reliable. Which was probably just as well ... imagine fault-finding amongst that lot!

Does anyone know if Dekatrons are stocked at Maplin's? think

There was an article on the Tv very recently about detector vans, they said that they were updating them for digital TVs but were keeping very quiet about the technology.
But surely the RF stage is very similar but just at a different frequency. So the vans may still be around somewhere.
You are supposed to have a licence for watching the BBC by any means including cable TV and on-line but how do they "detect" this sort of use?

Robert

Has anyone ever actually seen one of these vans in action?
Do they really exist except in BBC information films?

You can be sure that if "they" wanted to pursue "non-licence payers" these days, the work would be farmed out to Serco, Capitas, G4S (or some other such quasi-governmental "agency" of dubious competence). frown

As I may have mentioned before, I have not owned a TV set for many years (over 23 now, at least), and so have some experience of threatening letters, and all the rest.

Although Urban Legend (myths?) would have it that "snoops" are indeed about, it makes you wonder how they actually go about it. Listening at the door, perhaps?

Maybe they have someone rummaging through wheelie bins for discarded copies of the TV Times (or whatever it's known as these days). Who knows?

"Looking for TV aerials" is another I have heard about. But how can that be any good in blocks of flats, or indeed "dwellings in multiple occupancy"?

I'm pretty sure that the whole thing is just another example of frightening folk into coughing up the "Licence" fee. In other words:- scaremongering. Not that we would know anything about that on this forum, of course. whistle

Rojo - my understanding of how the 'old type' TV detector vans used to work and thus know you had a TV is this: People in the van will fire an RF signal at your property. If you have a TV, the local oscillator on the TV will pick up the signal and re-radiate it. As you know, the local oscillator is at a pre-set frequency, and if your TV re-radiates the signal - hey presto, you have a TV. It doesn't even need to be on, they are just looking for a re-radiated signal. The best way to stop it would have been to shield the local oscillator, but that's another story. It's not rocket science but I can understand how they would like to keep it from becoming public knowledge.
How it works with digital - no idea.

Meanwhile, someone else has advised me as follows:-

Quote:

TV detection with the 625 Line system was based on the line timebase high voltage transformer LOPT's (Line Out Put Transformer) electromagnetic field. It produced considerable radiation; for a good 50 feet or more. So using a BBC receiver within the van to monitor the off-air signal via its line-time-base on a 'scope, you could detect the radiation from the TV within a house, and identify the channel it was receiving by comparing the two signals. Today however, it's impossible to detect any useful signal from a flat screen TV, where radiation from any local oscillator is well screened, and no line timebase to detect any more. What TV's, and other domestic products, radiate is wide spectrum hash-noise. And if these also use SMPS's (Switched Mode Power Supply) - they wipe out most HF Short-wave reception and low band too.

The computer mouse is 50 years old and it inventor has just died.
He was one of the men with that special spark and imagination that made computing what it is today.
Here is how the mouse got its name, and this is the first mouse demo.

One by one the (true) Legends are falling by the wayside. frown

Like most geniuses, Doug was a visionary. He was way ahead of everyone else. Not only the mouse, but also the concept of "windows". He also actually built the stuff he dreamed up.

And yet his "manager" still asked:- "why are you funding this guy"? boggle

For a slightly different take, see this one.

Here is an interesting article on the start of office automation and computing.
I read the opening paragraphs
Quote:
Do you remember the office before email? Before we spent our time watching cat videos and doing surreptitious grocery shopping online?

As an experiment I turned off my office computer and kept it all off all day. I found I could think - just about - but had nothing to think about. I couldn't work, or communicate. I couldn't even skive. I was a non-person.
and thought "How true"

From the same article..

Quote:
Computers are so clever that it sometimes feels as if they do our thinking for us.


No, never, computers are the dumbest machines of all time, they only do what they are told (despite what it may seem like at times).

I, however, do remember what it was like before (oh god, I'm soooooooooo old tired). The fax, now that was a revolution. No more dependency on the horrors or the postal system and, clearly, anything that came off the magic machine must be of high importance and must be dealt with NOW.

That being said, email, spreadsheets, databases etc (with the possible exception of Power Point) are great tools, but only tools. They have increased the pace of business and, if used well, the ability to provide a quality business/service but, we need to be selective and concentrate on the important stuff.

But then, that has always been what we should be doing.

I won't be reading the article, as (from the quotes we have seen) it was obviously written by a clueless "modern" person. frown

@Dave: yes, the fax was a great leap forward ... but some of us have actually used a Telex machine! smile

Can't help you there, I'm afraid, Ed. The last time I sent a telex would have been from Nigeria in 1984. frown

But (and on the other hand), people tell me that telex is still used in certain types of secure (maritime, financial, maybe) international communications. As you know, you actually get an acknowledgement that your message has been received.

How's this for a bunch of clones! boggle

Someone once told me that the Russians still used Speccy clones to run their nuclear power stations (or whatever), but I had no idea there were so many!

Maybe they just got fed up with mail order stuff that never arrived, out-of-box failures, or some such thing. frown
