Abstract

The system control adapter (SCA) of U.S. Patent 4,023,142 has a number of diagnostic interfaces to other units forming part of the computer system. The Stuck Fault Diagnostic Wrap Test provides a method for testing the system control adapter and interface lines prior to using the interface functionally so as to assure correct operation and reliable results of any diagnostic test performed on an attached unit.
