The ABC not being general purpose (a term I use because it was used often in the book I referenced) is common knowledge. From it's Wikipedia page: "Conceived in 1937, the machine was not programmable, being designed only to solve systems of linear equations." http://en.wikipedia.org/wiki/Atanasoff%E2%80%93Berry_Compute...

I suggest you read the book I referenced - the relationship with von Neumann was not straight forward, either. Mauchly clearly did get ideas from Atansoff - but the ENIAC was not just a straight copy of ABC. Eckertt and Mauchly innovated as well - as much as we expect anyone to when we say they "invented" something.
