| Sony made a bedside alarm clock-radio back in the 80's--actually
| two models, a mono- and a stereophonic--that had a rare feature
| that I loved: you set the alarm with two dedicated and detented
| knobs, one to set the hour, and one to set the 5-minute mark for
| the alarm, and the alarm could be the radio. I would have the
| alarm go off every morning to either a classical or npr (back
| when it was listenable :) station. I loved that I could set the
| alarm just by reaching out in the dark and turning the knobs, as
| I could tell by feel what they were set to.
|
| for at least 15 years I kept this alarm clock with me as I moved
| cities a couple times. Unfortunately, the nixie tubes for the
| time display went bad so it became hard then impossible to read
| the numbers. I struggled with that for awhile, then I realized, I
| didn't care to read what time it displayed, I just needed the
| alarm to work. So, I would unplug it (and the 9V battery backup)
| and plug it all back in at midnight; A broken clock being right
| twice a day, that's the time it would assume. Got to use my
| favorite stereo radio for a number of additional years. It even
| lasted into my subsequent and on-going "I will never buy anything
| from Sony, ever again" boycott :)

| guess it wasn't nixie, some type of gas flourescent though. also,
| 24 hr clock so I guess it was right once a day.
