Zenith's LightSpeed Writer - 'Steno machine' is a myth?

[menuhin]

There has not been much I can find about this 'Steno machine' keyboard, called Zenith's LightSpeed Writer.


First, who invented and tested this peculiar layout and typing system? Zenith?
It is also said that a world record holder of "360 wpm and 7x National speed champion" used this keyboard (!?) Does that mean on average 6 words per second? Is this a reasonable speed?

So far, no one ever appears to have this keyboard at the $3000+ price point.

So now as a non-frequent gamer, I have one more reason to have NKRO keyboards, and the ErgoDox as it is officially supported by this open source project.
