JF Ptak Science Books Quick Post
I’ve found a supplement to an earlier computer tree that I published on this blog (here) as a part of a chronological list of (nearly every) computer manufactured from 1943 to 1990. The new one is interesting and has its differences from its predecessor, and divides its generations of computers in terms of logic technology. It is found in a 1960 NSF pamphlet called “The Family Tree of Computer Design”, a Brief Summary of Computer Development, and I found its reference in a good book by I.B. Cohen, Howard Aiken, Portrait of a Computer Pioneer, published by MIT and available here.

The earlier “Computer Tree”, from Electronic Computers Within the Ordnance Corps , by Karl Kempf. “U.S. Army Diagram”, the source of this information coming from the U.S. Army, here.
