The first video recording and playing machines for professional use appeared in the 1950s. Since the late 1960s, electronic firms together with broadcasting companies have worked on equipement for home use.
In the mid 1970s, Betamax and VHS emerged as widely adopted competing standards, of which the latter became the ultimate victor. VHS was extremely successful, before sinking into obsolescence after the introduction of the DVD and digital video recorders around the turn of the millenium.

But before the world settled on VHS, a plethora of different formats was developed. One of these was called 'Electronic Video Recording' or EVR for short.
Nintendo used this system in a number of its arcade cabinets.

Two different lines were created based on the EVR technology: EVR Race and EVR Baseball.
They were released in 1975 by Nintendo Leisure System (任天堂レジャーシステム).
EVR Race was available as horse race game or as sports car race game, depending on the tapes loaded into it. Cabinets were available for different numbers of players, from one up to ten. The version shown here accommodates five players.
Essentially a betting simulation, in EVR Race players would pick the horse (or car) they expected to win, then watch a randomly selected prerecorded race. After the finish they are rewarded based on the outcome of the race and the odds assigned to the horse (or car) at the start.

In previous arcade game systems (Laser Clay Shooting System, Simulation System) Nintendo had used various image projection methods, including use of 16mm film.
With EVR Race they started incorporting video technology for the first time.
The EVR system is an interesting mix of film and video technology.
Where most video tape systems use magnetic tape, EVR tape was actually more simliar to regular film, with frames of visible images. In the case of EVR these frames were not developed photographically but 'written' using a technique called electron beam recording.
During playback, the tape would be projected on a light-sensitive device inside the EVR player, which then converted the image into a video signal that could be displayed on a regular TV set.

EVR was originally developed by US broadcasting company CBS. Development was led by Peter Carl Goldmark, the man behind the LP record.
A number of global companies rallied behind the format, seeking world wide success, including a Japanese joint venture called Nippon EVR Ltd.

Nippon EVR Ltd. consisted of Teijin Ltd, Hitachi Ltd, Mitsubishi Electric and Mainichi Broadcasting System Inc.
Nintendo developed the EVR arcade system together with Mitsubishi Electric.

Even though it was called Electronic Video Recording, EVR only allowed playback. It was not possible to record yourself. This was done at a dedicated processing facility.

The EVR system produced high quality color video, but never really caught on.
And Nintendo? They soon dropped their attention from experimenting with exotic projection methods and followed the industry in creating video arcade games based on micro-processor technology, like Computer Othello.
CALLING ALL STATIONS: is there anyone out there with a working EVR player, who could play these tapes?
