It has 16 32-bit       registers, and uses a microprogram to define an instruction set of 154       instructions. Originally only 16 bits        were available for addressing memory; later this was extended with four bits       from the program status word register, allowing a directly addressable memory       range of 1M locations."              "The Space Shuttle used five AP-101 computers as general-purpose computers       (GPCs). Four operated in sync, for redundancy, while the fifth was a backup       running software written independently. The Shuttle's guidance, navigation and       control software was        written in HAL/S, a special-purpose high-level programming language, while       much of the operating system and low-level utility software was written in       assembly language. AP-101s used by the US Air Force are mostly programmed in       JOVIAL, such as the system        found on the B-1B Lancer bomber."              https://en.wikipedia.org/wiki/IBM_System/4_Pi              Joe              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
