Abstract
Handshake circuitry for an asynchronous bus interface system transferring data between first and second computer systems including apparatus for providing signals to indicate to the second computer system that the first system desires to read data at a specified adress of the second system, apparatus for comparing the specified address with addresses of the second system to provide outputs indicating the time required to retrieve data from the specified address, and apparatus operative in response to the output indicating the time required to retrieve data from the second computer to indicate to the first computer system the time at which the information will be available for transfer to the first computer system.
