The following is from a earlier posting I downloaded from USENET (but never had
to use thank goodness)




The Sad Mac error code is six digits long. The first two digits are the 
class code, and tell what the problem is. The second four digits are usually
meaningless except to repair people (they pinpoint suspected bad chips), but
for class code 0F, the codes are important. See below.

The Sad Mac codes are:

	01 nnnn 	ROM test failed.
	02 nnnn		Memory test (Bus sub-test) failed
	03 nnnn		Memory test (byte write) failed
	04 nnnn		Memory test (Mod3 test) failed
	05 nnnn		Memory test (Address uniqueness) failed

Class code 0F indicates failures after the self test at startup:

	0F 0001		Bus error
	0F 0002		Address error
	0F 0003		Illegal instruction
	0F 0004		Zero divide
	0F 0005		Check instruction
	0F 0006		TrapV instruction
	0F 0007		Privilege violation
	0F 0008		Trace 
	0F 0009		Line 1010
	0F 000A		Line 1111
	0F 000B		Other exceptions
	0F 000D		NMI.

All of these codes, by the way, are reason to gnash one's teeth, and pull
one's hair, EXCEPT 0F000D. This probably means that the programmer's switch
is jammed. Unjamming this switch should improve things dramatically.

Good luck to all. Clip and save this posting. Thank you.
