Circuit board for computing devices

The innovation concerns a circuit board or card with metallized holes and connections for the recording of integrated circuits and other circuit elements. Such circuit boards are suitable for Digital computers that are specifically designed to control the computer's program interruption. According to the innovation The circuit board is equipped with all the accessories necessary to connect the board to the digital computer the functions to be fulfilled is required.

The importance of circuits in the execution of digital computers is known. According to the determination of the computer and the functions to be fulfilled by it, as well as taking into account the input and output data of the computer, efforts are made to develop circuits which the provided Meet requirements optimally.

The implementation of the circuits envisaged is based on a set of plates of a certain size generally mounted on a frame. The number and type of plates arranged on the frame depend on the ι ΊΓ OL / j to be solved. CIa

Numerous circuit boards have already been developed, manufactured and put on the market for certain Zv.'cke; they are manufactured in a conventional manner, for example in the form of printed circuits with metallized holes.

According to the respective function, the circuit boards are used to accommodate a certain number of integrated Circuits, mixed circuits or certain 3 components. The present announcement relates to such a plate, which especially for controlling the program interruption of the computer

local overload and excessive density be avoided.

This is achieved in that the rectangular formwork panel is divided into narrow, slightly large individual fields running parallel to its narrow sides, each of which has connections along its side lines for confusion with other circuit boards or with the terminals is provided for the circuit parts provided for the circuit board, with a field being occupied by a maximum of three and at least two integrated circuits with approximately the same number of connections, and with up to eight resistors and at least one capacitor being removed instead of one integrated circuit board , while between integrated circuits arranged in adjacent springs there is at most one capacitor or resistor.

The circuit board described above allows a particularly interesting connection of the digital computer within the framework of the the function assigned to the plate.

The plate shown in Figure 1 was used in executed on a specific computer; it is assumed that the framework of the innovation is not covered by a plate is left, in which the schematic course of the connections or the position of the connections and other components relative to Figure 1 for purely formal reasons, for example with regard to a change in the plate size, is modified.
