The automatic sequence controlled calculator — II

The second in a series of three articles, this article continues a discussion of the functions of the automatic sequence controlled calculator developed at Harvard University in co-operation with the International Business Machines Corporation. The calculator will carry out any selected sequence of the five fundamental operations of arithmetic (addition, subtraction, multiplication, division, and reference to tables of previously computed results) under completely automatic control. The functions considered herein are those of the multiplication and division registers and of the functional units.
