Abstract :
The arithmetic element of the IBM Type 701 Computer contains a number of innovations, both in circuits and in logic, which distinguish it from that used in other high-speed, parallel, binary computers. The most significant of these is the storage element used in the arithmetic registers, in place of the more usual flip-flop or trigger circuit. Use of this new element enables a number of simplifications to be introduced in the methods of executing instructions.
