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.

I have one of the books published by Harvard that describe the operation of their Mark 1-4 series accumulators, just attempted to skim it...not easy stuff. The book is on display in the cabinet by the door at Kennett Classic Bill On Fri, Oct 9, 2020 at 12:48 PM W. Bryan Caudle via vcf-midatlantic < vcf-midatlantic(a)lists.vcfed.org> wrote: > Greetings!
