A Masterpiece of Japanese Engineering: The 1973 Casio √121-S "Root" Calculator

Own a significant piece of computing history. Released in 1973, the Casio √121-S was a high-end professional desktop calculator that represented the pinnacle of Casio’s early electronic innovation. Originally retailing for a substantial 59,000 JPY—a small fortune in the early 70s—this machine was designed for serious mathematical work, featuring a then-revolutionary square root (√) function.

Technical & Aesthetic Excellence:

Luminous VFD Display: Features a brilliant 12-digit Vacuum Fluorescent Display (VFD) that emits the iconic, warm blue-green glow highly coveted by retro-tech collectors.

Mid-Century Design: The bold black and white industrial chassis, complemented by vibrant red, blue, and tactile black keys, makes it a stunning centerpiece for any modern or vintage-themed office.

Authentic Heritage: Proudly "Made in Japan" by Casio Computer Co., Ltd..

Complete Collector's Set: This listing is exceptional due to the inclusion of its original accessories:

Original Manual: A rare Japanese instruction booklet providing historical context.

Protective Soft Case: The original black branded Casio dust cover.

Integrated Power Cord: Ready for immediate use.

Condition Report:

Functionality: Fully tested and operational. The display is bright and clear, and the mechanical feedback of the keys remains excellent.

Aesthetics: Well-preserved vintage condition. Shows minor signs of careful use over its 50-year history, adding to its authentic "Showa Retro" patina.

For the connoisseur of industrial design or the pioneer of digital history, the √121-S is an essential acquisition that bridges the gap between mechanical calculation and the modern computer age.
