In the future I hope you are as diligent to make note of the actual first electronic digital (binary) computer developed in 1939 at Iowa State University, as you are at perpetuating the notion that Eniac was the first by the inclusion of the modifier "general-purpose" and the exclusion that it was a decimal computer. The plans for general purpose use (and numerical integration) existed for the ABC computer, but WWII interfered with the implementation.

Thank you,
