DESIGN OF A COMPUTER ESPECIALLY ADAPTED TO THE STUDY OF THE PROPERTIES OF THIN FILMS
Abstract
SCALE MODEL OF THE ARITHMETIC AND LOGICAL PART OF THE COMPUTER: This part executes the following functions: algebraic sums, transfer from the coder into a register, nor alization, and cadrage. The noise introduced by the impedance of the power supply lines was reduced by lowering their resistance and by passing them by large capacitors. CENTRAL CONTROL: A program was written with which to test the functioning of the magnetic drum and to experiment with the adaptation of the computer to its memory. THE INITIAL ORDERS: Addresses (300) are used in the program for instructions, data, and partial results. Not all of the 300 will have to be filled in manually. It will be sufficient to send to the memory (by means of the coder and a register) the sequence of instructions and data necessary to form instructions and to place them at successive addresses. THE BUFFER: A Model FL Flexowriter constitutes the input and output part of the computer. The input and output signals for the Flexowriter are shown by diagram. A logical scheme is given for the buffer which connects the Flexowriter to the computer.
