Radio Speaker Like Chandelier
LOUD speakers which are placed in or on top of your receiving set cabinet are now being supplanted by a new amplifier that hangs from the ceiling like a beautiful metal chandelier.
The new amplifier is made up of a number of tone tubes which not only amplify the sounds but also give musical notes a rich tone. Each tube tones one note. Any electrical connection may be used between receiving set and chandelier.

RESEARCH MAKES THE DIFFERENCEUnlike ordinary Citizens Band transceivers, there are certain distinct advantages in owning the SONY CB-901 fully transistorized unit.

By HAROLD P. STRAND
SURE THEY WORK—and you don’t even need batteries! What are they? Just a pair of sound-powered telephones that are certain to turn a couple of kids into a pair of happy hooligans for many a fun-time session. And what’s the secret?

Pneumatic Tubes Carry Correspondence Through Office Building
INTER-OFFICE correspondence is shunted about from one. floor to another with lightning-like rapidity, thanks to the pneumatic-tube system of transferring messages, recently installed in the new skyscraper of a New York insurance company. The various tubes shown in the photo below lead to different offices in the building. If a message from the fifth floor must go to an office on the twelfth, it is shot to the dispatching room shown in the picture, where attendants insert it in the proper tube and it is pneumatically delivered to its destination.
RADIO LINKS SINGER AND ORCHESTRA
Convalescing from injuries received in an automobile accident, a radio performer recently sang to her audience from a room in a Philadelphia hospital, while she listened through headphones to an accompaniment played by a dance orchestra in a plane flying 5,000 feet overhead. A dual hook-up enabled listeners-in to hear the voice of the star perfectly blended with the music.

“What! No Kitchen Telephone?”
Of all things, Mr. Bridegroom! Surely you don’t expect that lovely new bride to get along without a telephone in the kitchen!

My first modem was an external 300 baud Hayes connected to an Apple IIc (there was no place inside to stick one). Man, even in 1987 300 buad was slow. It was easy to out type the display. Later, in high school I ran my own BBS, on a Supra 14.4, one of the fancy ones with the vacuum fluorescent display. I still cringe when I think about all of the hours I spent tweaking the Hayes initialization string to get everything working right.
