摘要:
A procedure for bringing-up and/or establishing the operability of a distributive data processing system comprises the steps of providing, at each terminal of said system, a display having a plurality of individually activatable indicators and/or indicia configured in a predetermined geometrical pattern with the position in the pattern and the electrical state of each indicator being representative of the operational readiness of an assigned terminal; running a series of operational tests in each terminal and selectively enabling the indicator and/or displaying an alphanumeric character representing said terminal on the successful completion of the operability tests.
