This manual provides a detailed technical guide for the operation of the Address-Writing Feature used with the IBM 407 Accounting Machine. The manual explains how punched-card data is converted into high-speed printed address tape, outlines functional principles such as tape feeding, carbon-paper handling, and multi-line address printing, and documents supported addressing methods including three-line and four-line formats. Illustrated with photographs, wiring diagrams, planning charts, and worked examples, the book is intended for operators and technicians responsible for configuring, wiring, and operating IBM punched-card accounting equipment in large-scale mailing and addressing applications.
The covers of the book has a former owner’s name written on the front cover in pen and the number 821 handwritten in red marker. The covers show very minor wear in several places but the binding is secure and all pages are intact and legible, with minimal signs of wear or discolouration.
