A bit off topic here, but the IBM 407 lives on as the "spec" stage in the CMS Pipelines utility. From the reference document: "Rest assured that no hardware knowledge is required to use spec effectively. But you will have a head start if you have past experience with the IBM 407 Accounting Machine, which influenced the design of spec." Spec is basically the 407 implemented in software. See: https://www.vm.ibm.com/library/720pdfs/72625201.pdf for more details. DJ
