Abstract: 988,085. Programming arrangements for computers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 15, 1962 [Feb. 15, 1961], No. 5572/61. Drawings to Specification. Heading G4A. In a digital electric calculator which comprises a number of registers each operable under the control of timing impulses to receive data on a set of common drive lines and to make data available on a set of common sense lines at predetermined times in the cycle of operation, the selected lines of the set of sense lines are shared by a control matrix itself operable under control of the timing impulses to deliver data to the sense lines, and the latter are connected to temporary storage means operable to transfer information carried by the sense lines to the drive lines. The invention is primarily concerned with microprogramming. A microprogram usually consists of the sense lines threading a column of cores of the control matrix, and it is necessary to increment only a so-called y-address at each step of the microprogram to select the next control core. This is done automatically by the means described in Specification 981,780. Changing the x-address requires a special micro-order. A description is given of the operation of the control system in a small digital computor having a keyboard data entry, and a typewriter for program tape input and for output. The arithmetic unit consists of a subtractor matrix working to radix 12. There is a main core store having yaddress registers A, B, a working store having y-address registers, P, Q together with single respective x-address registers, an arithmetic register T and a set of condition cores an appropriate one of which is set when a specific condition (negative signa, over flow &c. exists. The P.Q. registers are also arithmetic registers. There is described in some detail with reference to Figs. 1 to 6 (not shown) a 21-point operating cycle for each microinstruction in which the following operations are carried out: 1. Store to register, or register to store,transfer. 2. Subtract P or Q from arithmetic register T. Result to T. 3. Load constant into P or Q. 4. Select next microinstruction, with or without conditional branching. The subtraction matrix consists of an array of magnetic cores the row and column selection lines representing the operands and sense lines threading those cores at the intersection of selection lines representing numbers having the same difference (Fig. 7 not shown). A microprogram is initiated from the input program tape which carries the address of the first control core.

Abstract: 964,775. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 23, 1960 [Nov. 23, 1959], No. 39710/59. Heading H3B. A frame for mounting the cores of a magnetic storage matrix comprises a rectangular sheet of an elastic plastic material, e.g. " Alkathene " (Registered Trade Mark),- moulded to provide a lattice of support members, the members being arranged in pairs so as to define square apertures in which the cores are retained elastically and smaller rectangular apertures for accommodating the core wiring. The frame may include terminals on its outside edges and may be provided with a perforated rigid support during the moulding- operation.
