The IBM 405 Alphabetical Accounting Machine, 1934. This was IBM's high-end tabulator offering (and the first one to be called an Accounting Machine), complementing its numeric-only 285. The 405 was programmed by a removeable plugboard with over 1600 functionally significant "hubs", with access to up to 16 accumulators, the machine could tabulate at a rate of 150 cards per minute, or tabulate and print at 80 cpm. The print unit contained 88 type bars, the leftmost 43 for alphanumeric characters and the other 45 for digits only. The 405 was IBM's flagship product until after World War II (in which the 405 was used not only as a tabulator but also as the I/O device for top-secret relay calculators built by IBM for the US Army Signal Corps in 1943, used for decrypting German and Japanese coded messages [40]). In 1952, IBM first used core memory in an experimental 405 model [4].

Herb Grosch recalls of his early days at Columbia University's Watson Lab [57]: "About equipment: after merging in the better machines from the [Astronomical Computing Bureau in the] Pupin attic (I kept the old 285 horizontal tabulator as long as Marjorie [Severy] had room for it, out of sheer wonder at its clumsiness), we had two machine rooms with sorters and reproducers and collators, an interpreter, a gang punch, and several key punches. The most expensive machine (renting for over $1000 a month with all the bells and whistles I could hang on it) was the huge 405 tabulator, with 80 characters of alphanumeric storage, eating and disgorging 150 80-character cards a minute, printing 80 characters wide a line at a time (the type bars were too long to do this at full speed, but other models could print numbers only, at 150 lines a minute or 200 digits a second; the earth shook!)."

Use this link for as long as it lasts to see the machine room sequence, which lasts about two minutes.
• The film Wing and a Prayer (Henry Hathaway, 1944) for a brief look at the 405's card-feed and printing mechanisms in operation, as well as an IBM Radiotype and an IBM 032 card punch.

Commentary

I received the following email from "Strontium Black Cat" a.k.a. "Henry" in November 2018:

On your "The IBM 405 Alphabetical Accounting Machine" web page under the "Also see:" header it is stated that:

• "The film Infinity (Matthew Broderick, 1996), a story of the Los Alamos years of Richard Feynman, for a brief look at a 405 in action (the machine in the film might be a 402, which was not introduced until 1948)."

  I found the film on YouTube (with an overbearing Russian audio translation on top - but hey - it's the image that we are most interested in) "infinity бесконечность 1996 {En Rus алаб}" https://www.youtube.com/watch?v=upqbgWDZQzI.

  Starting at the following movie time stamps:

  01:02:27 IBM 403 (appears NOT to be the IBM 402 as suggested above - see clip)
  01:02:44 IBM 75? (card sorter)
  01:03:08 IBM 26? (card punch which 026.html states was introduced in July 1949! )
  01:03:38 (shows bits of IBM equipment in foreground and background)
  01:03:53 (shows a lot more of the IBM 75? in the background)
  01:20:24 IBM 26? (card punch)

• I found Wing and Prayer on YouTube: "Uma Asa e uma Prece 1944 Leg Dana Andrews Don Ameche" https://www.youtube.com/watch?v=-vfrTcbCEx4 - IBM 405 in operation - time stamp 01:08:02 - 01:08:19

(Me again, Frank) Following up on this... THIS LINK (for as long as it lasts) takes you directly to the sequence of interest in Wing and a Prayer, and I took some screenshots:

Receiving the message

Taking it to the decoding room

Punching the message onto cards

The IBM 032 card punch

The IBM 405

Putting the cards into the 405 hopper

IBM 405 type bars in action

Printed page comes out

Printing complete

Clearly neither the 032 nor the 405 could decrypt the message, so how does it come out of the 405 in clear text? What is not shown in the film is that the 405 is merely the i/o device for an unseen top-secret IBM relay calculator that decrypts the message.
