The author wanted to make it clear who he thought invented the computer. So much so that the last 50 pages of this book dealt less with ENIAC and more with his effort to overwhelm the reader with facts supporting his case. One can get that idea across in 5 pages without getting beaten over the head with it in the remaining 45. You've made your point, move on.The book was quite readable although in workmanlike prose and yes, the author has a valid arguement that John Mauchly and Presper Eckert should have received more credit for their invention. But for me this book didn't spend enough time on the scientific aspects and devoted too many pages over the squabbling of who built the first computer.
