Great article, as they all are! Two comments: (1) Typo: "acquired Zenith Data Systems form Bull", and (2) some numbers are written out but would be more easily read if shown as numeric (e.g., "the diode count to seventeen thousand three forty three" --> "the diode count to 17,343").

Quick notice: there is significant disagreement about the 2201 being the first fully-operation, transistorized computer to be publicly demonstrated. Of note, TRADIC from Bell was demonstrated to the public on the 16th of September in 1956 at the Institute of Radio Engineers Convention in New York City. The TRADIC, as far as I can tell, was absolutely the first fully transistorized computer, and it was publicly demonstrated in a fully working state. The sources for my statement about the 2201 made this claim, and I passed it on. I believe that the correct statement here would be that the 2201 was the first commercially available, fully transistorized, fully operational computer to have been demonstrated to the public as opposed to a single customer, governmental organization, or similar body. This is a much narrower achievement, but it is still quite notable. TRADIC was built by Bell for the USAF and was not a generally available commercial product. I wouldn't exactly refer to the 2201 as having been mass produced, but there was more than one 2201 while there was precisely one TRADIC. This notice will make into a house keeping update, and the article itself will be amended.
