Electronic calculator, roughly the size of an adding machine, came out much earlier. Nixie tubes.

Nope, not that much earlier.

Yeah it was.

No it wasnt. It has to be after 64

We may still have it :-(

Irrevant to when it first showed up.

* The digital watch (1972)

Pulsars -- red LEDs of some sort -- came out in the early 60s.

Nope, later than that.

Nope yourself. Well, maybe they took that long to hit Oz, but I
remember being at a gas station in Bakersfield and asking a guy to
push the button on his Pulsar. This is before our first kid was born
in 1964.

That must be your altzhiemer's talking, the Pulsar LED watch was only a prototype in 1970.

And that says that they were out of the price of the consumer until 1975.

We also acquired a stray calico kitten there, which we gave
to my mother-in-law. She was an exceptionally good cat, and now
Bakersfield cats have assumed a position of superiority in our family.

I wondering what the significance is with regard to using sheets from the magazines with regard to wrapping food. I know you are
not suppose to use newspaper. But is it alright to use the magazine sheets for wrapping food? Also are they both alright to use
in garden composting? This question is also relevant when using dampened magazine sheets to clean down food surfaces and clean
windows etc.

Would anyone know how to explain simply how the method of printing is done differently between the magazines and the newspapers?
Thanks for any advice.

I think you only need to use your nose: though with widespread colour the line between magazine and newspaper is increasingly
blurred. Most magazines smell horrible, and many give me a headache, therefore the ink isn't dry, and you don't want it in your
food. (Some may be done on photocopiers, but even cured plastic toner can transfer on to say over head projector slides if you
leave them stacked together too long.) I'm a bit out of date but one of the more headachy solvents I used to hate and smell in
magazines was cyclohexanone. There are large numbers of inks and formulations as there is still a touch of alchemy involved.
Many magazines still have ink that doesn't dry completely and you can quite often get a reversed image if you insert a piece of
plastic and weigh it down for a while. You probably don't smudge it because most of the time your fingers are on the border of a
magazine whereas you tend to touch the ink when you are folding the newspaper to read it.

Shiny magazine paper is a pain to anyone who likes to make notes in margins etc. as biro smudges all over the place and pencil
either won't write on it or rips it to pieces.

Clutch-head security screws. Saw them on TW in the 70s I think.
Never saw them in the wild for years, now they are a common sight fastening
public toilet cubical panels together.

I can remember a few others that did too... Not necessarily that fast.

Ronstrip. Or rather the same sort of caustic gunk applied to a large wooden
area, coated with a blanket then pulled off an hour or so later, paint and
all. I guess that form would never had made it in the market, but I'm almost
certain Ronstrip must be the practical derivative.

Talking-telephone-computer-menus: I saw that when I was a kid - thought:
wow, an actual computer talking to you. Never guessed how bloody annoying it
would be @-|

Sure they must have done quite a bit on "self driving cars" which whilst
that happened, look at the parking assist and the safety-distance-brake that
are on quite a lot of cars now.

I used an electronic calculator with Nixie tubes in 1962 at
University.
Quite possbly this model:
http://en.wikipedia.org/wiki/Sumlock_ANITA_calculator

Ours had a normal 10-key keyboard plus the usual memory functions. It
cost $100 at The Akron, a store long out of business which sold neat and
interesting stuff at really low prices. I can't remember how much the
regular-brand calcs cost, but it was a lot more.

Even were the printing processes identical for newspapers and the magazines,
you would still find a marked difference in the extent their pages soil your
fingers during handling. Most newspapers still use an oil-based ink, the oil
being a slow-drying hydrocarbon solvent, and it takes days to evaporate.
For the articles in newspapers to be current, they are usually printed on the
morning that you read them, meaning their ink has not had a chance to dry.
The supplements, on the other hand, are printed days ahead and the solvent
in their ink has had plenty of time to dry (almost).

Historically, inks have contained traces of toxic substances, especially the
coloured inks, and I expect that in some countries that is still the case.
But here in Australia, I have not heard anyone caution against the use of
newpapers or magazines for gardens and composting. Presumably, the industry
here is regulated to use only non-toxic inks. (The same does not apply to
dyes in inks and cosmetics imported from China.)

The search for a more environmentally-friendly printers ink has been a topic
of much discussion over the years in our local daily, where invariably the
response has been that available water-based inks still have one or more
shortcomings in comparison with the traditional oil-based product. Only
recently was it announced that an acceptable substitute has been developed.

I don't know whether it's the ink, or the fibrous paper itself, which gives
newspaper its recognised capacity to shine window panes and mirrors. Guess
I could discover for myself by tearing off a handful of unprinted sheet
borders and trying to polish a mirror with them. :-)

Would anyone know how to explain simply how the method of printing is done
differently between the magazines and the newspapers? Thanks for any
advice.

I can't address that as I don't know. Maybe someone else can or already has?

Because our fingers (i.e., our skin) secrete both natural oils and also water
(perspiration), we tend to get stained by dyes which are soluble in oil (i.e.
the stuff from 'permanent' markers) and also by dyes which are soluble in
water. The best (or worst) of both worlds, as it were.
