I'm not sure if this is the right place to ask, but still, some people here may know the answer.
I have been reading up on the history of photocomposition. I was wondering if the terms "first generation" and so on were accurate, since it seemed to me that machines such as the Intertype Fotosetter and the Monophoto would only have been made if the traditional hot-metal typesetting machine companies saw the handwriting on the wall.
While some sources called the Lumitype, also known as the Photon, the first phototypesetting machine, it dated from 1949, while the Intertype Fotosetter preceded it in 1946.
A somewhat later machine was the ATF Typesetter. Built from a modified Friden Justowriter, I would expect it to have been less expensive than other phototypesetters on the market, at least until quite a late date, after microprocessors would have lowered the cost of ancilliary electronics. So, since it didn't take over the world by storm, I wondered what its limitations might be.
I learned it offered typefaces in sizes from 5 1/2 points to 14 points. A result on Google Books in "snippet view" mentioned that the machine was available both in an 18-unit version and in a cheaper 7-unit version. I would strongly suspect that the original version was the 7-unit one, and then based on demand a newer version upgraded to 18 units was made, but I don't yet know this.
As it happens, I now have a copy of "The Encyclopedia of Type Faces", and was thus able to take a close look at a page with the ATF Typesetter version of Baskerville. The italics were the same width as the Roman.
I suspect that this wasn't because it just had the same limitation as the Linotype. Instead, I strongly suspect that, given its mechanical construction, like the IBM composer, it used the same allocation of units to each graphic for every typeface. But I have not yet been able to verify this.
I have run across some additional information. It turns out the patents for the machine were U. S. patents numbers 3,082,670 and 3,333,668, the inventor being one George J. H. Sausele.
