Computer Multiplexing

In order to obtain controlled bi-directional transfer of data between computers 1 and 2, counters 3 and 4 are connected between the input and output sections of the memories.

The counters are controlled by the computers and their counts are adjusted as the computers progress through programs of instructions. When the counter 3 reaches a first predetermined value, it causes the transfer of information from the output section 5 of the memory of computer 1 to the input section 6 of the memory of computer 2. When counter 3 reaches a second predetermined value, it causes computer 2 to process the received information in the input section of its memory in place of its current program.

Counter 4 operates in a similar manner to control the transfer of data from the output section 7 of the memory of computer 2 to the input section 8 of the memory of computer 1.
