Robert Garner scanned some card forms (that were in the 1401 frame itself), below. He believes they could be a record of the 1401's "Engineering Change Orders" (ECO's), but not sure at all. They record events from Dec, 1963 to Dec, 1964.

Arnold/Rolf, Hallo! Are these indeed a record of the 1401 CPU's ECO's? If not, what? Would you have an opportunity to translate the German? Especially "Anderungsstand," which I couldn't find on any on-line dictionary? Thanks! - Robert

and we received the reply from Arnold and Rolf Schweinsberg

Hello, Aenderungsstand is "last level of alternation" at this time, this is for a part number (Bauteilnummer). This is not equal to any engineering change. This seems not to be important for you. Greetings from Arnold and Rolf

Ed questions - should "alternation" be "alteration"?? I am making that substitution (below, in italics) until corrected.
