The 1962 print ad says "Potential speed becomes practical speed, thanks to a stroke storage system that releases type characters in sequence no matter how fast the typing."
I got curious about the "stroke storage system" - was it mechanical, electronic, or what?
The Wikipedia page has an explanation of this mechanical storage:
> The machine had a feature called "Stroke Storage" that prevented two keys from being depressed simultaneously. When a key was depressed, an interposer, beneath the keylever, was pushed down into a slotted tube full of small metal balls (called the "compensator tube") and spring latched. These balls were adjusted to have enough horizontal space for only one interposer to enter at a time. (Mechanisms much like this were used in keyboards for teleprinters before World War II.) If a typist pressed two keys simultaneously both interposers were blocked from entering the tube. Pressing two keys several milliseconds apart allows the first interposer to enter the tube, tripping a clutch which rotated a fluted shaft driving the interposer horizontally and out of the tube. The powered horizontal motion of the interposer selected the appropriate rotate and tilt of the printhead for character selection, but also made way for the second interposer to enter the tube some milliseconds later, well before the first character had been printed. While a full print cycle was 65 milliseconds this filtering and storage feature allowed the typist to depress keys in a more random fashion and still print the characters in the sequence entered.

I used it for my dissertation. The page numbering feature could not be adapted to my university's requirements, so I printed out my manuscript without page numbers, and pasted them in by hand, then had the whole thing photocopied.
For those interested in dance transcription, there is a formerly commercial but now freeware Windows product called Danceforms. http://www.charactermotion.com/df-download.html
I have an IBM Selectric that I purchased at a thrift store. It is a marvel engineering. It was too much to resist. I have not used it, but I tried it out. It works. It really is a fine machine. I think I will spin it up and exercise it.
I wonder if one of those dance type balls is available any where. I suppose not, but it would be fun to try it out.

There's one source of truth, Ann Guest, and some people are frustrated at not getting the most precise answers.

I remember the type all’s being such a part of pop culture that a televised game show, involving contestants identifying objects in a black bag by touch alone, were expected to identify a typeball as a common, everyday object.
