In a Nutshell
it turns you on even when it's turned off. You can hang it, you can swivel it in 3 dimensions, you can carry it like a handbag, you can power it 3 ways - and - oh, it comes in its original shipping box

Introduction:
On Oct. 4, 1957, the Soviet Union launched world's first satellite, Sputnik 1 into an orbit around planet earth, and 4 weeks later Sputnik 2 with dog Laika on board. This surprise success started the space race and what we today call the space age, succeeding but still being part of the atomic age, and precipitating the cold war between USSR and USA. First US launches (Vanguard) were disastrous, but the foundation of NASA in 1958 made missions like Pioneer 4, Mercury, Gemini, and finally Apollo great successes. The Apollo program was launched to do space exploration around (but not on) the Moon. Speaking to Congress and the Nation, President John F. Kennedy on May 25, 1961 radically altered the direction of the program by saying: "I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to Earth. No single space project in this period will be more impressive to mankind, or more important in the long-range exploration of space; and none will be so difficult or expensive to accomplish". The projected price tag was an incredible $25 billion dollars. On July 16-24, 1969 Apollo 11 (Columbia and Eagle) on a Saturn V with the astronauts Neil A. Armstrong (commander), Michael Collins (CM pilot), Edwin E. (Buzz) Aldrin Jr. (LM pilot) accomplished the first manned lunar landing and lunar surface exploration (EVA), watched by over 500 million people around the world. From then on, amplified by the Challenger and Columbia space shuttle accidents in 1986 and 2003 and the fall of the Soviet Union in 1991 public perception of space exploration got dominated by its dangers (Apollo 13, the Film 1995, "Houston, we have a problem") and costs (conspiracy advocates are still convinced that the moon landing was faked by using left-over scenes from Stanley Kubrick's 1968 movie "2001: A Space Odyssey"); space exploration shifted to unmanned missions and to the private sector, respectively. Scientific and military progress had triggered Googie and atomic age designs in architecture and industry and space age designs for basic commodities, fashion, music and arts. A prominent example is the 1957 flatware made by Arne Jacobsen (pict.22 of my Video Capsule writeup), used in the Space Odyssey and still sold after 57 years for $20 a piece on eBay.
The 1970 JVC Videosphere 3240 is the second of five space age TV's for sale. The theme is that of a space helmet supposedly inspired by the "Space Odyssey" (see above and pict. 23), and later featured in two other movies Conquest of The Planet of The Apes (1972) and The Matrix (1999). Unique features of this TV are a) that it rotates a complete 360 degrees in all directions, for full-picture viewing from any position, including headstand, b) a quick-start electronics ensuring an instant picture when the set is turned on, c) a possibility to power it with 12V DC, with a plug or a car battery, d) a decorative chain for carrying or suspending the TV. Quick-start is a mean trick of course, since the CRT power bypasses the on/off switch. So, please unplug the TV when not in use to spare the filaments.

About my Videosphere:
The TV is in mint visual and working condition. Out of the three available colors red, white and black red is the most appealing. The model number suffix MU (pict.s 19,21) stands for Canada (UK for Great Britain, GM for Germany, SC for Scandinavia, F for France, AUL for Australia, ...). The TV has its original shipping box with matching serial number and styrofoam stabilizers, in which it was shipped on Dec. 3, 1971 from Montreal to Victoria (pict.s 21,22). There are no scratches on the styrene cabinet nor on the smoke acrylic screen cover, no oxydation on the chain and antenna, the latter being original, complete and straight. The inside was cleaned and all moveable parts were treated with contact spray (pict.20). The set was tested with a VCR connected directly to the antenna with a piece of wire. The better way would be the use of a 75/300 ohm TV antenna transformer adapter, readily available in many thrift stores and on eBay. Watch a short video (click on pict.28) with the TV playing a section of "Casablanca". During the video volume, contrast and brightness tests are performed. The picture has good brightness and contrast and the sound is perfect. The blackened-out parts of the screen in some of the still photos are caused by missing synchronisation between camera and TV and are absent in live view.
