Abstract :
This paper gives a brief review of the design of the machine GIER (42-bit words, 1-k core store, 12-k drum store, 50-microsecond fixed point, 100-microsecond floating, add time) and its programming systems. The principal subjects are: The order structure, the operating system, the ALGOL 60 system, an evaluation of the order structure, the hardware organization, and the latest hardware extensions, including a hybrid computer system.
