Selector cornections for A/sub hi/ were simplified and the subtractor to be used during divide and floating point add, at the low ends of R and Q, was designed. The problem of decoding the range of "d" for the selection of a floating point addition sequence was investigated. The design of a memory element, the Reply Back Eccles-Jordon was completed. The circuits which drive large numbers of parallel diode-logic circuits were redesigned to reduce the ramber of driver types from 3 to 2. The second chassis of dropout detection equipment was constructed. Some results of a formulation of the emitter-follower oscillation theory and a study of the transient behavior of chains of transistor circuits are presented. Two IBM 650 sorting schemes using three magnetic tapes are described. An approximation to the exponential function was obtained. Various schemes for unnormalized floating point arithmetic were proposed. A description of eight new routines, added to the Illiac library, is given. Descriptions of one revised and four new routines which were added to the IBM 650 library are contained. (C.J.G.)
