Microvision

The Microvision was a hand-held game console released by Milton Bradley Company in 1979. The Microvision was designed by Jay Smith who later went on to design the famous Vectrex. Microvision's combination of a cartridge-based system and portability would surely be a success. In the first year, $8 million was grossed making Smith Engineering a million dollar industry. But very few cartridges, a small screen, and no backing-up by a conventional console lead to its demise in 1981. Image File history File linksMetadata Microvision2. ... Image File history File linksMetadata Microvision2. ... A handheld game console is a lightweight, portable, electronic device for playing video games. ...

Microvision units and cartridges are very rare nowadays. Time is taking its toll on the Microvision units still in existence. There are three main problems faced by Microvision owners: screen rot, ESD damage, and keypad destruction. To meet Wikipedias quality standards, this article or section may require cleanup. ...


The manufacturing process used to create the Microvision's LCD was primitive by today's standards. Poor sealing and impurities introduced during manufacture has resulted in a condition known as screen rot. The liquid crystal spontaneously leaks and permanently darkens, resulting in a game unit that still plays but is unable to properly draw the screen. While extreme heat (such as resulting from leaving the unit in the sun) can instantly destroy the screen, there is nothing that can be done to prevent screen rot in most Microvisions. It has been suggested that Color LCD be merged into this article or section. ...


A major design problem involves the fact that the microprocessor (which is inside the top of each cartridge) lacks ESD protection and is directly connected to the copper pins which normally connect the cartridge to the Microvision unit. If the user opens the protective sliding door that covers the pins, the processor can be exposed to any electric charge the user has built up. If the user has built up a substantial charge, the discharge can jump around the door's edge or pass through the door itself (dielectric breakdown). The low-voltage integrated circuit inside the cartridge is extremely ESD sensitive, and can be destroyed by an event of only a few dozen volts which cannot even be felt by the person delivering the fatal shock. To meet Wikipedias quality standards, this article or section may require cleanup. ... The term electrical breakdown has several similar but distinctly different meanings. ... Integrated circuit showing memory blocks, logic and input/output pads around the periphery A monolithic integrated circuit (also known as IC, microchip, silicon chip, computer chip or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) which has been manufactured in the surface...


Instead of having buttons on a separate controller, the Microvision unit had a twelve-button keypad, with the switches buried under a thick layer of flexible plastic. To align the user's fingers with the hidden buttons, the cartridges had cutouts in their bottom (over the keypad). As different games required different button functions, the cutouts were covered with a thin printed piece of plastic, which identified the buttons' functions in that game. The problem with this design is that pressing on the buttons stretched the printed plastic, resulting in the thin material stretching and eventually tearing. Having long fingernails exacerbated the condition.

The first Microvision cartridges were made with both Intel 8021 and Texas Instruments TMS1100 processors. Due to purchasing issues, Milton Bradley switched to using TMS1100 processors exclusively. The TMS1100 was a more primitive device, but offered more memory and lower power consumption than the 8021. First-revision Microvisions needed two batteries due to the 8021's higher power consumption, but later units (designed for the TMS1100) only had one active battery holder. Due to the high cost of changing production molds, Milton Bradley did not eliminate the second battery compartment, but instead removed its terminals and called it the spare battery holder.

It wasn't until 1984 when a true handheld system was made (Epoch with their Game Pocket Computer), and it wouldn't be until 1989 when a handheld system would have any success (Nintendo's Game Boy). The Game Boy system had a processor chip like any other computer, compared to the Microvision which lacked a CPU and needed one in every game cartridge, making game purchases more expensive than buying games for the Game Boy. 1984 (MCMLXXXIV) was a leap year starting on Sunday of the Gregorian calendar. ...
