GM solved this problem by using an approach developed by Boeing, replacing the milling head of a computerized milling machine with a ball-point pen and connecting the inputs of the mill to the 704 computer. To address the extremely limited amount of memory available on the 704, they broke the diagrams down into 32-by-32-inch squares, which ...
The GM-NAA I/O input/output system of General Motors and North American Aviation was the first operating system for the IBM 704 computer. [1] [2] It was created in 1956 by Robert L. Patrick of General Motors Research and Owen Mock of North American Aviation. [1] It was based on a system monitor created in 1955 by programmers of General Motors ...
A Regular Production Option (RPO) is a 3-digit standardized code used by General Motors to designate vehicle options & modifications. RPO codes designate how a vehicle is built, and they've been used on dealership order forms and in assembly plants since at least the 1950s (see Corvette C1).
It is an improvement on the General Motors GM-NAA I/O operating system, the first operating system for the IBM 704. The main objective was to improve the sharing of programs. The SHARE Operating System provided new methods to manage buffers and input/output devices. Like GM-NAA I/O, it allowed execution of programs written in assembly language.
PCM: Power-train control module (Ford, GM, JLR) ECM: Engine control module; Injection control unit (Peugeot, [2] Citroën, Fiat, Alfa, Lancia) DME/DDE: Digital Motor Electronics / Digital Diesel Electronics (BMW, [3] Mini) ECU: Electronic control unit / Engine control unit
While controlled or partially controlled by the Powertrain Control Module (PCM), third gear is used as a failsafe gear and default operating gear during unexpected conditions. Without computer control, the transmission will automatically hydraulically shift from first gear into second gear based on input shaft RPM.
GMT K2XX is an assembly code for a vehicle platform architecture developed by General Motors for its line of full-size trucks and large SUVs that started production with the 2014 model year.
The GM Technical Center was inaugurated in 1956 as General Motors's primary design and engineering center, located in Warren, Michigan. In 2000 the center was listed on the National Register of Historic Places , and fourteen years later it was designated a National Historic Landmark , primarily for its architecture.
