I remember the machines had a card where it was prominently
printed "GAMBLING PROHIBITED".

Actually, in the snackbar, people tended to play solo serially,
not much competition. I don't remember if the machine
supported two or four players. I remember people would put
their coins on the glass as a way of noting their place
in line to play next. The good players would rack up extra
games. I think if you were very good, once you won one game
it wasn't too hard to win more. I remember the game counter
incremented with a loud pop when someone racked up enough points.

It was just cool watching the skill of the players. Not only
jiggling the machine--but not tilting it--but also knowing
exactly when to hit the flippers for maximum effect and
direction. Since it was only one machine and people played
it regularly, they got to know it. But as mentioned, some
of the players frequented the arcades at the seashore and
built their skills up there as well.


In the 1970s 'Pong' came out. We thought that was
pretty neat. I knew an EE major who built his own
that hooked up to the TV.

In many locales where gambling was prohibited, the pins were configured
to not award free games or free balls.

It was common even in the age of film to take a lit shot for the
ordinary surfaces, and a dark shot for the illuminated elements,
and to merge them through darkroom trickery. It's just easier
with the new digital toys.

After all the playing I've done I'm not convinced of the utility
of jiggling the machine. I mainly use it to incite the pop bumpers to
bounce the ball around increasing score.

Supposedly you can nudge the machine forward and push a draining ball
up between the flippers. So far, no luck.

There are multiple ways to catch the ball, I'm pretty good at that.
If you don't catch the ball, most of what happens is random.
You can't see the spin on the ball so you never know exactly
where the ball is going next.
Once you can catch the ball, you can actually aim the ball somewhere.

I personally think that display image is not even from the calculator at all. Nixie tubes use thin (almost) wires which glow with fuzzy edges, that image has much too wide of lines with sharp edges. And the grayed-out zeros look entirely wrong as well. I suspect it is a type-set strip of digits superimposed on the calculator photo.

That being said, I can almost see the "3-D" effect of the digit wire-frames (where each digit is on a different z-plane) which gives the impression of crooked digits. So, makes me wonder if they just took paint/air brush/etc to the negative or print (filling-in/thickening the fuzzy neon digit glow).

I remember an arcade in Langley, BC, Canada which had a Galaxian
game. There was one guy who could get to level 200+. One evening,
the manager of the arcade gave him the usual warning that the arcade
was closing in about fifteen minutes and to finish his game. He said
that the manager should have warned him when he came in. They both
laughed.

Sincerely,

To me, the digits definitely seem to have the right shape for Nixie tube digits.
Plus, because the photograph is taken from "below" rather than perpendicular to
the digit plane, one can see that the 8 is in front of the 5, which is in front
of the 4, which is in front of the 1. *Definitely* a Nixie tube.

All right, then, why aren't the wires of the digits in front showing up?

Well, when taking a separate picture to superimpose for the digits, in addition
to over-exposing it a bit, one could also soften the focus. That would cover up
the thin wires. And use high-contrast film so this doesn't make the digits look
blurry.

Of course manual retouching with an airbrush or the like is also possible, but
there were options to minimize the amount of expensive manual work needed.

Yeah, how quickly I forget how resourceful we all were before the age of digital photography and hi-rez graphics. Of course, a scan of a magazine ad is probably never going to give us enough information. The display looks too clean for my memories, so definitely enhanced in some way. I never tried to photograph neon displays before digital cameras, and I'm certain I'm glad I didn't!

It was very common for images used in advertising to be retouched
in various ways, both in the darkroom and in post processing
(air brushing).

Film had limitations with contrast, so yes, it was common for
an image to be taken twice and merged together, with the two
images exposed for different settings.

Looks like it; some of the digits appear to be nearer to the viewer
than others.
