[GreenKeys] Inktronic/Dataspeed printer ink?

[Jim Haynes]

If I remember correctly Dataspeed was a word reserved for Bell System use.
The high speed punched paper tape systems e.g. Dataspeed Type 2 were
called Telespeed when sold by Teletype to non-Bell customers.  And
Inktronic was a Teletype Corp. name.  So I guess AT&T marketing people
decided the Inktronic belonged to the Dataspeed product line when being
promoted to Bell System users.

There have been some other oddities like this.  The last stock ticker was
based on Model 37 technology, but the AT&T manuals call it a Model 28
stock ticker.  Maybe they wanted to keep "Model 37" a pure term for 
up/low case machines.  And I don't think AT&T ever publicly acknowledged
the Model 29, calling the 29ASR a "Model 28 IDP ASR set" where IDP means
Integrated Data Processing.
