   general architecture with the System/360 mainframes. 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."

   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."
