Wirkungsweise des ungarischen Kommandogerätes GAMMA-JUHÁSZ
A detailed 28-page technical study (Winter 2014/15) by André Masson describing the design and operation of the Hungarian GAMMA-JUHÁSZ mechanical analog fire-control computer, which was adopted by Switzerland from 1937 and built under license by HASLER. The document covers the machine's geometric (non-Cartesian) computation principle, its ~400 kg gear-train architecture, form-body nonlinear function generators, electrical servo-tracking (micrometer) circuits, speed measurement subsystems, and successive model variants (Kgt. 38, 40, 43, 50), comparing the GAMMA-JUHÁSZ approach with the competing SPERRY system.
