[GreenKeys] Fwd: Unknown TTY ICs

[Lester Veenstra]

Why did they not just have Western Electric turn their designs into silicon?
 I assume WE had a much more efficient FAB faculty in operation.

Teletype did indeed make their own ICs in-house.  There is a book about
it, "Teletype, We Made That Data Move!" by Herbert A. (Tag) Waggener.
It was quite an accomplishment.  However it was probably a strategic
mistake for the company, in requiring a huge capital investment for a
product that in semiconductor industry measures was small quantity.
