TV Tag (Popular Electronics, November 1972, USA)
The earliest video game construction article known to
exist. This simple game was clearly inspired from one of the Magnavox
Odyssey games released to the public in May 1972. This game is also
very similar to the Chase Game invented by Ralph Baer in 1966, which
consisted of two spots chasing each other.
One of the two players disappeared when hit by the other. This
game shows the winner, unlike Ralph Baer's game which didn't do
so (but only hide the second player).
TV Football &
Others (Television Magasine, July 1974 to February 1975, England)
The whole project is split over seven
issues, each describing a precise part of the whole project. It starts with
the simplest form of the game and ends up in a quite advanced game with
several features added. The game
seen on the photo is a two player version which can produce pictures in color
when the television set is modified, and which generates amazing sound effects.
The best part is the last one from February 1975: it describes a special plug-in module which replaces a joystick
in order to play against the system. Simple and efficient, it is quite hard to
defeat. The obvious and amazing possibility of such a module is to
replace both joysticks to let the system play alone. Very few arcade versions
and home systems allowed playing against the machine. Amazingly, the module
was called 'superman' in the article...
To finish, it is still interesting to note that the seven articles explain
very clearly each part of the system: general aspects, how the objects
are generated on the screen, how the bounces are made, how the collision
detection works, etc... Thus, a good electronician could easily improve the
system. This great set of articles is one of the best as it
describes a rather advanced game which differs from the classic variants.
TV Tennis (Elektor, November 1975, March and May 1976, Europe)
The original article published in November 1975 features an analog game made with TTL chips.
It plays the classic Tennis game in its simplest form: only two paddles an ball.
Issues 11 from March 1976 and 13 from May 1976 featured improvements adding new games,
the central line, top and bottom boundaries, sound effects, on-screen scoring, and even
a solo mode to play against the machine which never looses.
Pongtronics & Space-War (Popular Electronics, April 1976, USA)
Two very interesting articles featuring different PONG variants.
The first article features a 3-game project named Pongtronics. One game is Handball
and the two others are Tennis variants, one of which is played with gravity
ball no longer bounces on all the screen edges but as in a real tennis game
The other project
is called Space-War (it has nothing in common with the original 1962 computer
game). Its game consists in shooting a missile (the Tennis ball) at the
opponent. Both players are represented by the usual Tennis paddles.
Pongtronics add-ons (Popular Electronics, May 1976, USA)
This Popular Electronics issue proposes an extension for the
Pongtronics project published in the previous issue: on-screen scoring and sound effects.
The interest of this
project is to explain how early forms of on-screen scoring (without digits)
Sound effects are added for bounces and scoring.
Video Ball (Electronics Australia, May 1976, Australia)
An interesting construction article offering 32 game variants
with unique effects, and designed with only 13 TTL chips.
Video Ball could also be ordered in kit form.
Ping-Pong with Bumper (Radio Electronics, June 1976, USA)
Another project which has two interesting points: the use of a large
square bumper, and the digital on-screen scoring. Yet we don't have the second issue
containing the schematics of the digital on-screen scoring and sound effects add-ons,
but this first part is still interesting for making the basic analog system.
ETI 804 (Electronics Today International, November 1976, Australia)
A typical issue covering a project based around the AY-3-8500 game
chip. This type of project has the interest of showing the simplicity of a system
based around the AY-3-8500, hence the success of that chip. ETI 804 was also
available in kit form.
TV Games in Color (Television Magasine, July 1977, England)
This interesting article contains the description of a
simple project based around the MM-57105 game chip from National Semiconductor.
Unlike most other hobbyist projects which generate a black and white picture, this
one generates a color picture. The article is split over the
July and August 1977 issues. It even makes a comparison with the General
chip in order to show the advantages of using the MM-57105 chip.
Like with some other projects, the circuit board could be ordered.
New Video Ball Game (Electronics Australia, July 1978, Australia)
New Video Ball game is a simple project based around the General Instruments AY-3-8600 chip.
It obviously replaces the initial Video Ball project published in May 1976.
Wipeout (Radio Electronics, September 1980, USA)
Based on the General Instruments AY-3-8606 chip, Wipeout plays ten variants of
the classic Breakout game for one or two players. Articles based on a dedicated
video game chip usually feature the classic Ball and Battle games. Here,
another General Instrument chip is used, which is quite rare. As with Ball and
Paddle games, this project shows how dedicated game chips simplified the
main electronic circuit and reduced the number of components required, hence
the global cost.
