Title: Improvements in or relating to data processing systems
IPC: G06F9/26
Filed: 1965-05-12
Abstract: 1,108,807. Micro-programming. INTERNATIONAL BUSINESS MACHINES CORPORATION. 12 May, 1965 [21 Dec., 1964], No. 19982/65. Heading G4A. In a data processor, micro-instructions are selected in intrisically restricted sequences by a first selection unit until receipt of a predetermined programme instruction which activates a second selection unit to select at least one micro-instruction and renders the first selection unit inactive during this selection. During conventional operation using the first selection unit the successor of any current micro-instruction may be selected from a set of from 1 to 16 micro-instructions, depending on machine conditions and bits from the programmed order code, although there are 2816 micro-instructions altogether. A " diagnose " programmed instruction will specify a base quantity and an index register, thereby providing a 16-bit quantity, 12 bits of which select one of the micro-instructions through the second selection unit, and of the other four bits, one is placed in a trigger to specify conditional or unconditional control (see below) and three are placed in a counting circuit. If control is unconditional, selection of micro-instructions reverts to the first selection unit after selection of the one micro-instruction mentioned and remains there until another " diagnose " programmed instruction is encountered. On the other hand, if control is conditional, selection reverts to the first unit as before but returns to the second unit after the first unit has selected a number of micro-instructions equal to the number specified in the counting circuit, which is decremented by one after each selection. When the count reaches zero, a predetermined constant micro-instruction is accessed to select the next programmed instruction in sequence. Thus " diagnose " instructions enable segments of micro-programmes to be executed. A " diagnose " instruction may initiate a so-called " kernel " micro-programme which is not accessible in any other way, control being transferred unconditionally to the first selection unit. The " kernel " micro-programme terminates when a micro-instruction in it accesses a micro-instruction outside it as the next microinstruction or transfers control to the second selection unit. Use of the " diagnose " instruction for producing an oscilloscope display of micro-instruction signals (including relative timing) for maintenance purposes, is described.

Abstract: 291,638. Wilden, A., and L÷wenthal, P. Aug. 2, 1927. Mechanical shooting-galleries. - A coin-freed shooting-apparatus is provided with a target disc f, Fig. 1, having an aperture i and carried by an arm g mounted on the axle h so that a shot missing the aperture and impacting on the disc tilts it backwardly. The disc is held in tilted position by a detent n engaging a shoulder p of a cam disc m on the axle h, until a coin is inserted, the disc, when tilted, covering a target plate l normally in alignment with the aperture i. A shot passing through the aperture hits the plate l and rocks a lever k which moves a ratchet lever s to turn a ratchet-disc u through the space of one tooth, backward movement of the disc u being prevented by a locking lever 26 pivoted at 16. After three successive hits a projection v on the disc u depresses a detent w and releases a spring-controlled rod x which can then be pressed in by a knob y, Fig. 2, at the front of the apparatus to deliver a prize or card from a magazine z. When the prize is delivered, the rod x acting through links 6, 7 tilts the target disc f so that another coin must be inserted. Each time the disc f is tilted, the levers s, 26 are raised by a link 8 connected to a weighted arm r carried by the axle h, thereby allowing the ratchet disc u to be returned by a weight 9. This ensures that a prize cannot be obtained except by successive hits. The stock 11 of the gun a is prevented from being fully broken to enable it to be reloaded, when the disc f is tilted, by a piece 13 which cannot be pushed in since a projection 17 on the axle h has allowed a detent 19 to engage a rod 15 connected by a lever 14 to the push-piece.
