The Haigh, et al article (3 parts) does not disprove the Manchester Baby as the first stored-program machine, nor claim to do so. And it neither shows nor claims the 48 ENIAC to be the first stored-program machine. Well, it doesn't explicitly make the claims, but it is rather curious that people interpret it as doing so. Quote from the article [pg5]: Should ENIAC therefore be considered the first operational stored-program computer? Well, it all depends on what we mean by ?stored program.? Which is what I said earlier. The article proclaims a set of criteria they call the "modern code paradigm" and claims the 48 ENIAC as the first machine to have fulfilled their criteria. Quote [pg13]: As we explained earlier, we do not view the modern code paradigm as a new name for the ?stored program concept?. Using the article to make a claim vis-a-vis "stored program" for the 48 ENIAC as disproving the Baby's widely regarded status is conflating the "stored-program concept" with some other meaning of "stored program", or creating your own definition of "stored-program concept", and misrepresenting the (stated) claims of the article. The Harvard Mark I stored programs, as a sequence of instructions recorded in a storage medium, and automatically executed them while reading from that medium, several years ahead of the 48 ENIAC, not to mention the conceptualisation of such for the Analytical Engine. That's not what you meant about storing a program? You mean you have other defining qualifiers? Harken yonder! I see grey clouds on the horizon.

As a claim of historical consequence for the 48 ENIAC however, it's just too much contrivance. Here's an alternative abstract: We look at the etymology of the phrase "stored program" and decide it's all so confusing, so we dismiss all the previous historical assessments [pg8-11]. We note as others have that declaring firsts in history is problematic as it inevitably comes down to providing a string of qualifying descriptors [pg9]. To avoid these problems, we define a set of conceptual elements from the Draft Report on the EDVAC, to form a new set of criteria of assessment. We call this set of criteria the "modern code paradigm" [pg12]. We find that the 48 ENIAC fulfills our set of criteria. We now declare the 48 ENIAC to have been the first machine to fulfill the modern code paradigm [pg15]. (See page-long string of qualifying descriptors defining the modern code paradigm [pg12-13]). What about that little issue of writeable program storage? That little characteristic that is rather seminal to computing ever since 1946, and (previous) meanings of "stored-program" all included, but an element that the 48 ENIAC did not have ? That was dismissed because it wasn't used in the ways the Draft Report described it (to be) used. But it's also dismissed because the ways it did come to be used were NOT described in the Draft Report. [pg10-11] Meanwhile, other criteria were included even though they weren't done the way described in the Draft Report. What? And the 48 ENIAC wins ! Huh. What a coincidence. The authors could have just written an article about the 48 ENIAC with a comparison of it's programming characteristics to modern programming, but they just had to also attempt to dismiss the "stored-program concept" of historical relevance, while nonetheless leaving everyone they proselytise to conflating the "modern code paradigm" with "stored program". Yup, they sure did clear out all the confusion, not added to it. It's just another attempt to make an historical claim for the ENIAC, this time trying to steal the light away from the Manchester Baby. Sorry, no sale. I could go on but I have to pick up my newly tailored suit and a gallon of facts.
