IAS

   1.  The first modern computer.  It had main
   registers, processing circuits, information paths within the
   central processing unit, and used Von Neumann's
   fetch-execute cycle.

   The IAS machine's basic unit of information was a 40-bit
   word and the memory had 4096 words.  A word stored in memory
   could represent either an instruction or data.  Each IAS
   instruction was twenty bits long, so that two instructions
   could be stored in each 40-bit memory location.  Each
   instruction consisted of an 8-bit operation code and a
   12-bit address that could identify any of 2^12 locations that
   may be used to store an operand of the instruction.

   The CPU consisted of a data processing unit and a program
   control unit.  It contained various processing and control
   circuits along with a set of high-speed registers for the
   temporary storage of instructions, memory addresses, and data.

   The main actions specified by instructions were performed by
   the arithmetic-logic circuits of the data processing unit.  An
   electronic clock circuit was used to generate the signals
   needed to synchronise the operation of the different parts of
   the system.
