• If a failure code for an I/O bus address or data line occurs, remove
the related assemblies one at a time until the failure message
disappears. Be sure to turn the analyzer power off while removing
and installing each assembly.
If the failure message disappears, suspect the assembly that was
removed last.
If the failure message remains after all related assemblies have
been removed, suspect the A16 assembly.
• If a A16 video RAM fail code occurs, the A16 assembly is defective.
