Zenith "Memory Timer" clock radio

[Jeffhs]

Zenith, back in the '50s or early '60s I believe, manufactured and marketed a clock radio it termed the "Memory Timer". The clock could be set to wake the user five days a week at a set time, but skip weekends and/or holidays. How did that clock work? I don't think any other radio manufacturer of that era had radios with that kind of sophisticated timer clock forty or fifty years ago. The Zenith Memory Timer radio must have been fairly rare, as I've only seen two of them in my life so far--one was owned by a great-aunt of mine in the '60s, while I spotted the other one on ebay a couple years ago. My great-aunt got rid of her set years ago (I don't know for sure why anymore, but I think the radio still worked at the time while the clock had finally given up the ghost), which I think was a terrible loss since it probably would have been a collector's item or museum piece today. As I said, no other manufacturer of clock radios, that I know of anyhow, ever copied the Memory Timer design, probably because the clock may have been a one-of-a-kind design specially made for Zenith.
