A Proposed Modification to the C.S.I.R.O. Mark I Computer

Abstract

The order code of the C.S.I.R.O. Mark I computer, as described by Pearcey and Hill in their recent papers (1953a, 1953b, 1954), is already more extensive and flexible than that of any other machine of which a description has been published. It still offers some scope for expansion, however, and it is the purpose of this note to put forward one particular suggestion for the addition of an entirely new type of order. "General purpose" computers, so-called, are at present by no means so general in their application as users would desire, and broadly speaking there are two types of attack on this problem.
