The Specification is a development of Specification 905,614 in which the working relationship between two or more computers is controlled by counters, one counter linking each pair of computers. The present Specification links a pair of computers by two counters one of which (counter A, Fig. 1a) controls transfer of data in one direction (computer Y to computer X) and the other counter controls transfer in the other direction. Of the computers described, computer X is a relatively large computer having its own input/ output control by which the states of counters A and B are known at all times, while computers Y is a smaller computer, assigned the task of converting input data from magnetic tape to a form suitable for computer X and the reverse process, and must be programmed to sense the states of counters A and B. The memories of each computer have parts assigned to data which is to be input or output of the computer. Each part has seven sections. The setting of counter A indicates the number of sections in the input part of computer X which are free to receive data from computer Y. The setting of counter B indicates the number of sections in the input part of computer Y which are free to receive data from computer X. Flow sheets of the programs of computers X and Y are shown in Figs. 10a and 10b (not shown) and are thought to be self explanatory. The Specification describes in some detail control circuits for performing the operations indicated in Figs. 10a and 10b.
