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 generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control Module (BCM), for a total of three separate computers. These automotive computers are generally very reliable.
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.
The Vortec 2200 (RPO code L43) is an OHV straight-4 truck engine. This engine is equipped with secondary air injection, and is flex-fuel capable. It is entirely different from the Iron Duke, and was the last North American iteration of the GM 122 engine. The 2200 uses an iron block and aluminum two-valve cylinder head.
