1750A
The 1750A isn't a particular computer, but a family of compatible computers that implement the instruction set described by the military standard document MIL-STD-1750A, (1980). The computers have been constructed by many methods, by a wide variety of companies. Traditionally, 1750s run aircraft, missiles or parts thereof. They are usually programmed in JOVIAL, a high-level programming language similar to Algol.The U.S. Air Force defined the standard in order to reduce the costs of software and computer systems for aircraft and missiles.
The 1750 usually has a 16-bit bus, and 2^16 16-bit words of memory. Most op-codes are 16 bits, although some have a 16-bit extension. The standard computer has 16 general purpose 16-bit registers. Registers 13 through 16 can be used as index registers. The computer has instructions for 16, and 32-bit binary arithmetic, as well as 32 and 48 bit floating point. I/O is generally via the I/O instructions, whcih may have a specialized bus and separate address space.
