Interesting story. I was looking at the (very nice) one on eBay (202637078233). Fascinating machine. I don’t see a card reading mechanism - was that a peripheral? Sent from my iPad > On Oct 11, 2020, at 5:09 AM, Jeffrey Jonas via vcf-midatlantic <vcf-midatlantic(a)lists.vcfed.org> wrote: >

RE: [vcf-midatlantic] Looking for some knowledgeable with the Harvard Mark I
by Jim Scheef 09 Oct '20

Bryan, I do not represent to be a resource on these machines but have read many books on the history of computing. Most of what I've read about the Mark I was in books with chapters on Howard Aiken or Grace Hopper. I seem to recall that the Charles J. Bashe/Emerson W. Pugh book about early IBM machines, IBM's Early Computers (1985), had some information. My memory sort of distills down to the factoid that the Mark I had almost no ability to branch in a "program" owing to the instructions being read from a rather wide punched tape and thus being sequential. I suspect your friend is looking for more depth, but the bibliographies of these books may put him on the right trail.
