Once upon a time, this was probably as "technical" as it got.
Someone put it out to the pasture alley, 2 weeks ago.
Then, someone else put this book on it, 2 days ago.
It breaks my heart, but they shoot horses for less!

ADD: I thought to strip the keys of their ivory content but that would be unethical or a felony.
 
Radio... Tape... Spot... Oh, my!
Not Kansas... but Quincy!

...Gates reported selling 55 units at the [1959] show for $850 each (about $9,300 in 2025).
By 1961, Gates claimed in a trade magazine ad that 500 stations were using the ST-101.
The 1962 Gates General Catalog described the ST-101 as storing 101 announcements, each up to 90 seconds long, on a 13-inch-wide magnetic tape.
An index lever was used to select the desired cut and playback could then be started.
When the 90-second cut finished, a photoelectric cell reversed the motor, rewinding the tape in 22 seconds.
Individual tracks could be erased and re-recorded.
The ST-101 had:
*A specified tape speed of 5-1/4 inches per second,
*A frequency response of 50Hz–8kHz ±2dB,
*An SNR of 45dB or better,
*A distortion below 2%, and
*A wow & flutter below 0.35%.
It used five vacuum tubes.

They moved 'my' goal post and I am not happy!
I blew a few MOV devices, when I recently learned that:
