In 1987, Casio released the TM-100, a most unusual digital watch. On the surface, it appears to be a normal time-telling model but de*p inside Casio embedded circuitry to transmit audio signals. Flip the little lever above the display, raise the telescopic antenna and speak or play music into the little microphone and the TM-100 will broadcast the audio to nearby radios! A tiny tuning kn*b allows you to calibrate the preferred frequency on the FM band (specifically, the Japanese FM band which is 76-90MHz and a portion of the US FM band, 87.5-108MHz). The case is all plastic and it requires two batteries, one for the timekeeping feature and one for the transmitter. To us, the TM-100 is partially shrouded in mystery. We have never seen it advertised and it is a relatively uncommon watch. The transmitter feature was never included in any other model. We know of a few gadgets sold in Japan (the birthplace of karaoke!) included a transmitter but no wristw*tch. Does anyone have any information? Our friend akitaishi posted a couple of very cool videos of his Casio TM-100 in action! Witness a most interesting marriage of technologies: the source is an iPod with digital audio files, playing into the Casio TM-100 and broadcast over FM into a clas*ic ’80s boombox. After cleaning out my closet recently, I re-discovered this little Citizen credit-card sized LCD clock and became amazed all over again. I’ve had this little thing for at least 20 years, it was one of the earliest things I’d purchased in one of my weekend jaunts to NYC. If I had to guess on the year of manufacture, I would say 1984. I presume this little gadget was marketed to the businessman who at the time could not rely on email, online chat or video conferencing to get his job done. Meetings of international business were always face-to-face and required time-consuming and expensive travel. So, “world time” was a popular feature in clocks and wristw*tches. Not much larger than a stack of credit cards, this little plastic device is controlled by pressure-sensitive membrane bu*tons to control
