Core Memory Weavers: Exercises in Computing Labor History
The Women Who Threaded the First Digital Memories

Book Details
About this book:

Core Memory Weavers: Exercises in Computing Labor History Step into the hidden workshop of the digital age, where the first computers were not coded on screens but stitched by hand—millions of tiny ferrite rings threaded by women whose names vanished from the technical record. *Core Memory Weavers* reveals how these “needleworkers of the machine” built the magnetic cores that powered mainframes, defense systems, and the Apollo guidance computer, turning a domestic craft into the foundation of modern computing.

Through vivid chapters that trace the physics of core memory, the ergonomics of micro‑assembly, the global supply chains of Cold‑War factories, and the fierce struggles for recognition and union rights, the book restores a vital, gendered labor history to the center of tech storytelling. Each section pairs rigorous scholarship with hands‑on exercises—from analyzing archival diagrams to attempting your own core‑threading simulation—so you don’t just read about the past; you feel the tension of a wire through a 13‑mil ferrite ring and understand why every bit was a triumph of human dexterity.

By uncovering the erased signatures of the core memory weavers, this book offers a powerful lens for today’s invisible tech workforce—data labelers, cleanroom technicians, content moderators—reminding us that the digital world has always been built on real hands, real bodies, and real struggles. Dive in, and see the thread that still runs through every chip, every algorithm, and every click.
