Proposed revised American standard code for information interchange

communications at dec, and had just been doing research at mit, so it wouldn't be terribly surprising if he, or friends of his from mit or dec, were to sit on the ansi (then asa) committee mackenzie's 'coded character sets' from 01980 has a chapter 13 about ascii https://textfiles.meulie.net/bitsaved/Books/Mackenzie_CodedC... but unfortunately it doesn't go into any detail on the composition of the asa committee. note that mackenzie was the ibm thug who invented ebcdic and spent the 60s and 70s trying to kill ascii, so he devotes most of the book to glorifying that catastrophic error; the book is from 01980, the year before ibm shipped its first ascii-supporting equipment, the ibm pc. it's reasonable to see jennings's account as a violent reaction against mackenzie's book, writing the malignant influence of the punched-card codes out of history entirely, though, as we'll see, the original draft of ascii was designed by a punched-card man bell's oral history interviews https://www.computerhistory.org/collections/catalog/10270203... don't mention ascii or asa or ansi, so he probably wasn't on the committee, but if it was a connivance by a friend of his, it would be easy to imagine him deliberately not mentioning it https://dl.acm.org/doi/pdf/10.1145/363831.363839 is an early (01965) publication of what eventually became ascii-1967, but it doesn't list the subcommittee members; the subcommittee seems to have been x3.2 at that point, though the 01963 document was called x3.4-1963 http://edition.cnn.com/TECH/computing/9907/06/1963.idg/ says the original proposal was submitted to ansi (though other sources say ansi didn't exist yet) by bob bemer of ibm in 01961. i thought it would be interesting to see if it already had ^g for bel, because bemer would be unlikely to know bell at that point in 02002 bemer wrote a 52-page history of ascii himself called 'a story of ascii' https://archive.org/details/ascii-bemer which includes a survey of coded character sets from 01960, including the character set used on the 'lincolnwriter' at mit, where bell had been working, and the pdp-1 for which bell designed the uart, as well as another 40 or so. so it wasn't like there was no contact. as it happens, neither of those two character sets includes a bell character the bell character appears in the first version of the ascii proposal in the leftmost column of table 3 on page 17 — but at position 10, from which it was moved to its current position of 7 (^g) after four revisions (iso/tc97 wg b, 01962 may 4, following x3.2/1, which was 01961 september 18). his only comment on why they moved all the control characters around was, 'the controls were regularized and grouped to 7 transmission controls, 6 format effectors, and 5 device controls; the improvement from the haphazardness of the previous proposals is quite apparent.' this was shortly before ibm sent him to the penalty box for promoting ascii, leading to him quitting to go to univac at that point there was still disagreement about whether to start the alphabet at the beginning of a 16-codepoint 'column' or, as is done today, one character later, so that a corresponds to 1, b corresponds to 2, etc. so assigning bel to 7 could have ended up with it being ^h. (i'm not clear on whether the ctrl key existed yet, but i'm pretty sure bit-paired keyboards did, on the teletype.) unfortunately bemer is also largely silent on the membership of the committee, though he does mention particular members from time to time. unless i've overlooked it, he doesn't mention anyone from mit or dec. the iso meeting was an international thing, with delegations from the us and various european countries, and thus seems particularly unlikely to have redesigned the character set to honor a dec engineer, who the committee members would think of as an american engineer so it's probably just a coincidence, but the evidence i've been able to turn up is not very conclusive
