Amazing Computer Called MRS (Dec, 1958)

Wow! This was a stunningly advanced computer for the time. I think it would give HAL a run for his money.

MRS

A temperamental MRS computer doesn’t always follow instructions—and self-programs a surprise that only another computer could understand

By Hugh B. Brous, JR.

FIRST OFF, let me tell you that the MRS is no off-the-shelf commercial computer. MRS stands for Multipurpose Research System, and we designed and built the whole works ourselves at the Research Institute. Consequently, we can blame only ourselves for the design features that led to all the troubles. Everyone on the staff still feels that the basic concepts are sound but we unanimously agree that some changes will have to be made before MRS can be a dependable computer system.

MRS is a well-built hunk of hardware with just about everything a computerman could want. She’s got microprograming, built-in compiling routines, half a billion words of high-speed memory, a basic pulse rate of a micromicrosecond, and fantastically fast input-output scanners that work with a whole printed page at a time.

Miniature Cars are Practical (Feb, 1935)

I really wish people still drove around in these. I certainly would pay extra for a pizza delivered by a little kid wearing a cap, driving tiny car.

Miniature Cars are Practical
CHEAP and serviceable, this little car has attained much favor in England. It goes only 15 miles an hour, but can be driven by a child, and is obviously easy to maneuver and park. Weight, 200 pounds; balloon tires, 12-inch diameter. It is cheap to run —and taxes (based on power) are very low. It is even used for sales display as a miniature of larger cars, with bodies on a reduced scale. In spite of a juvenile appearance, it is quite serviceable for commercial and individual use. Control is by a single pedal.

Put An Outboard Motor On Your Bike (Feb, 1943)

… Or Put An Outboard Motor On Your Bike…
AN ATTACK on the trans– portation problem from a different angle has been made by G. E. Griffin, of Vass, N. C, at left. Mr. Griffin has attached a 3/4 h.p. aircooled outboard motor to his bicycle, the shaft geared by friction directly to the rear tire. He reports that the arrangement works very well, can do 30 m.p.h. or even better, and doesn’t appear to wear the rear tire badly at all.

Soviet Engineers Building 80-foot “Glider” Boat (Nov, 1937)

Soviet Engineers Building 80-foot “Glider” Boat
SOVIET engineers are constructing a “glider” speedboat for service on the Black Sea. The boat will have two hulls and carry 150 people at a speed of over 40 m.p.h. Four aviation motors of 675 horsepower each will power the novel craft, which will be 80 feet long with a width of 40 feet. A model of the boat has been placed on public exhibition in Paris, France.

Early Radar (Oct, 1935)

MYSTERY RAYS “SEE” Enemy Aircraft
AMERICAN and German War Departments announce simultaneously new rays capable of “seeing” enemy aircraft through fog, clouds, or dark, at distances of up to fifty miles. First tests in this country are being held at the Lighthouse Station near Highlands, N. J., by the War Department, the details of the invention being closely guarded by military police.

No larger than a penny match box is the German mystery ray machine, a highly-perfected ultra-short wave radio transmitter.

Groups of these transmitters, mounted along the border of a country and adjusted to send their “feeler” beams into the sky at a fixed angle, could be used for air defense. The 5 to 15 centimeter long beams act much like invisible light rays, and are reflected back to earth by aircraft.

Groups of ultra-short wave receivers stationed some distance from the transmitters would pick up one or more of the beams reflected. With each transmitter sending out a different type of signal, something like the interrupted signal produced by a dial telephone, and each receiver connected to the central switchboard, the distance and height of the plane could be calculated automatically and almost instantly by a machine built to interpret optical and trigonometrical formulas. With this data, air defense guns could be aimed accurately at the unseen targets.

Hotel Guests DIAL for Radio Programs (Aug, 1935)

This is pretty sweet.

Hotel Guests DIAL for Radio Programs
HOMESICK foreign guests at New York City’s Waldorf-Astoria hotel can now listen to radio programs from their own country, or perhaps even from their home town. At their service is the greatest all-wave radio receiver in the world—a set which can bring to each of the 2,200 suites of rooms programs from any one of the powerful broadcasting stations in the world. These programs are oftentimes heard with the same volume and clarity as are local stations.

Some rooms have a unique dialing system, which permits guests to select any station they desire from a printed daily list of world-wide broadcasts, or even hear their favorite phonograph records. In other rooms there are controls on the modernistic loudspeaker, which give to guests a choice of six broadcasts. Amplifiers build up the strength of weak signals more than a hundred billion times.

Radio Listens In On Phone Calls (Jul, 1936)

Radio Listens In On Phone Calls
AN ELECTRICAL eavesdropper, the invention of a Washington, D. C, man, Samuel S. Hixon, permits the listening in on phone conversations without connecting to the line. The device, operating on the radio principle, is capable of picking up conversation from phone wires within a radius of twenty-five feet without tapping lines.

Kansas Girl Genius Operates Television-Radio Station (Jun, 1936)

Yeah, well, she’s pretty smart, for a girl.

Kansas Girl Genius Operates Television-Radio Station
CONQUERING fields in which very few men have ventured eighteen-year-old Eleanor Thomas of Kansas City, Mo., is assistant engineer of Television station W9XBY. Finding the life on a college campus too prosaic Miss Thomas, a mathematical genius for a girl, decided to leave and enter an engineering school.

Throughout the course the young woman excelled in her studies and upon her graduation she was appointed to the position she now holds. She is the youngest member of her sex ever to pass the difficult examinations for a first class operator’s license from the Federal Communications Commission.
