Nope. 0F0003 is an illegal instruction. 0F000D is the programmers switch.

All the codes, as I have them:

	01xxxx		ROM test failed
	02nnnn		Mem test (Bus sub test)
	03nnnn		Mem test (Byte write)
	04nnnn		Mem test (Mod 3 test)
	05nnnn		Mem test (Addr uniqueness)		
	0F0001		Bus error
	0F0002		Address error
	0F0003		Illegal instruction
	0F0004		Zero divide
	0F0005		Check instruction
	0F0006		TrapV instruction
	0F0007		Privilege violation
	0F0008		Trace
	0F0009		Line 1010
	0F000A		Line 1111
	0F000B		"Other exceptions"
	0F000D		NMI

nnnn, when it appears, tells the bad chips. It is a bit map, the bit
number set corresponds to the suspect chip.


Do I guarantee this information? No way, bud.
