Page "Accumulator (computing)" Paragraph 9

:" The first part of our arithmetic organ ... should be a parallel storage organ which can receive a number and add it to the one already in it, which is also able to clear its contents and which can store what it contains.

We will call such an organ an Accumulator.

It is quite conventional in principle in past and present computing machines of the most varied types, e. g. desk multipliers, standard IBM counters, more modern relay machines, the ENIAC " ( Goldstine and von Neumann, 1946 ; p. 98 in Bell and Newell 1971 ).
