Jason that early tablet was quite different from the HyperBraille. It displayed an entire DOS page of 80 characters by 25 lines and took up an entire desk. And it cost quite a bit more than US$100,000. Three were sold, or maybe only two with one being given free to the University of Stuttgart. And at least a few cells were broken at any given time. Wonder why it did not become more popular.

In fairness, the Hyperbraille is a lot more practical, and the price may eventually be a lot less than $100,000, but it would still be very surprising if the price got low enough that anybody but researchers could afford it.

In the mid 1990s, if I remember correctly, someone associated with the University of Stuttgart mentioned a price for these devices of approximately DM 100000. (Obviously, this was before Germany switched to the Euro.) It appears that the cost hasn't improved since then, and nor has the availability. That's what I meant by "research prototypes".
