[GreenKeys] An Introduction to Teleprinters and Punched Tape Equipment

[Sam Hallas]

I've just finished a major recreation of this 52-page booklet from
ITT-Creed, dated 1958.

It describes all the current equipment, which was based on the Model 54.
The 'new' Model 75 gets a very brief mention.

There are a lot of photographs, which explains the rather large file
size of 2.5 MB.

I trust it will be of interest to list members.

Cheers,
Sam
