History

The Vectrex was conceived by John Ross of Smith Engineering in late 1980.Barton, Matt and Loguidice, Bill. (2007)

(CRT) and wondered if a small electronic game could be made of it. A demonstration of a vector-drawing cathode ray tube display was made by connecting the deflection yoke in a standard television to the channels of a stereo amplifier fed with music program material. An auxiliary yoke was used to keep the raster television's horizontal fly-back high-voltage system running. The demo led to a system originally conceived as a handheld called the Mini Arcade but, as Smith Engineering shopped the idea around to developers, it evolved into a tabletop with nine-inch screen. The system was licensed to General Consumer Electronics in 1981. After a brief hardware and software development period, the Vectrex was unveiled on 7 June 1982 at the Summer Consumer Electronics Show in Chicago. It was publicly released in November at a retail price of US$199, just in time for the holidays. The launch sales were strong enough that Milton Bradley bought out General Consumer Electronics in early 1983. Milton Bradley's greater resources allowed the Vectrex to be released in parts of Europe by mid-1983 and, through a co-branding agreement with

turned Milton Bradley's support of the Vectrex into a costly mistake, even despite reducing its price by 25% and then later 50% in desperation to sell units. In February 1984, after losing $31.6 million on the Vectrex, Milton Bradley announced the discontinuation of the console and cancelled development of new games. The company's entire inventory of consoles and accessories was sold off to mass-market discount houses, where they were liquidated at a fraction of the console's introductory price. By May 1984, Milton Bradley merged with

Design

The computer and vector generator were designed by Gerry Karr. The computer runs the game's computer code, watches the user's inputs, runs the sound generator, and controls the vector generator to make the screen drawings. The vector generator is an all-analog design using two integrators: X and Y. The computer sets the integration rates using a digital-to-analog converter. The computer controls the integration time by momentarily closing electronic analog switches within the operational-amplifier based integrator circuits. Voltage ramps are produced that the monitor uses to steer the electron beam over the face of the phosphor screen of the cathode ray tube. Another signal is generated that controls the brightness of the line. The cathode ray tube is a

Early units have a very audible "buzzing" from the built-in speaker that reacts to the graphics generated on screen. This is due to improper production grounding of signal lines of the low-level audio circuitry, and was eventually resolved in later production models.

Peripherals

The 3-D Imager, invented by John Ross, turns the 2-D black-and-white images drawn by the Vectrex into a color 3-D experience. The imager works by spinning a disk in front of the viewer's eyes. The disk is black for 180 degrees and in some cases has 60 degree wedges of transparent red, green, and blue filters. The user looks through this to the Vectrex screen. The Vectrex synchronizes the rotation of the disk to the software frame rate as it draws 6 screens: with the right eye covered: the left eye red image, then green, and then the blue image is drawn, and then, while the left eye is covered by the black 180-degree sector: the right eye red, green, and then the blue image is drawn. Only one eye will see the Vectrex screen and its 3 associated images (or colors) at any one time while the other will be blocked by the 180-degree mask. The prototype was made in the plastic casework of a Viewmaster. The disc spins freely and is driven by a motor. The Vectrex software generates its own frame-rate and compares it to an index signal from the glasses once per revolution. Score is kept of how many wheel rotations are early compared to the software frame rate, and how many are late. The software tries to keep these two trends equal by adjusting the power being delivered to the motor that spins the filter and mask wheel. Pulse Width Modulation (PWM) is used to control the motor speed: the ratio of the "on" time versus the "off" time of a rapid stream of power pulses to the motor. In this way the software synchronizes the wheel rotation to the software's frame rate, or drawing time, for the combined and repeating group of up to 6 evolving images. A single object that does not lie on the plane of the monitor (''i.e.'', in front of or into the monitor) is drawn at least twice to provide information for each eye. The distance between the duplicate images and the angles from which they are drawn will determine where the object will appear to "be" in 3-D space. The 3-D illusion is also enhanced by adjusting the brightness of the object (dimming objects in the background). Spinning the disk at a high enough speed will fool the viewer's eyes/brain into thinking that the multiple images it is seeing are two different views of the same object due to the persistence of vision. This creates the impression of 3-D and color. The same 3-D effect is in fact possible with raster or film-projection images, and the shutter glasses used in some 3-D theaters and virtual reality theme park rides work on the same principle. The light pen allows the user to "draw", to create images and to indicate, on the screen. It has a photo-detector that can see the bright spot of the vector-drawing display monitor when it goes by under the light pen's position where it is being held to the screen. The photo-detector feeds internal pulse-catching circuits that tell the Vectrex and its software of the event. The prototype was made in the plastic casework of a Marks-A-Lot felt-tipped marker pen. The Vectrex draws a spider-web-like search-pattern to track the pen's location. The software changes the pattern size as the pen changes motions and velocity in an attempt keep a continuous lock on the pen's position. The Vectrex light pen was invented by John Ross.


Screen overlays

In order to enhance the display visuals of the Vectrex, every commercially released game included its own unique translucent plastic screen overlay that accompanied the cartridge (a concept first seen with the Magnavox Odyssey, as well as some early arcade machines). Instead of physically touching the CRT screen, four tabs on the Vectrex console securely held them in place in front of it, with a small gap between the actual screen and the overlay. Made up of one to three colors for the play field area, these overlays provide the illusion of simple color graphics (on an otherwise black and white screen), helped reduced glare, flicker and gave the appearance of a flat screen. They also allowed changes in brightness intensity of vector graphics to be more visually distinctive. In some cases game designers created pseudo color cycling effects, for a sense of movement, by using alternating colored patterns. In addition to players' score areas, some overlays also contained additional artwork and patterns, to add to the game's play field. Across the bottom of each overlay are game-specific joystick and button functions as a guide for the player. Each overlay also displayed the title and logo of each game, along with a colored border or design, to add cosmetic flair to the Vectrex (much like an arcade machine with its marquee or side art). Overlays were not required, but added to the experience in terms of the visual look of game graphics and the overall display appearance of the console.
