Maintenance Panel Error Code Summary for Xerox 1108 Interlisp-D 

There are two types of maintenance panel codes:	 progress codes and error codes.  Progress codes are placed in the Maintenance Panel at various stages of initialization.  Error codes are traps which freeze or blink the error number in the maintenance panel.  They are all fatal errors.

0000-0499 boot-time diagnostics
0500-0699 IOP code
0700-0899 Pilot microcode
0900-0999 Pilot
1000-6999 tech-rep diagnostics
7000-8887 Star
