80000004 means illegal instruction. The second number is the address of the task which abended. Without a memory dump (or access to the memory at the time of the crash) one cannot tell which one it is.

Do get more info about the guru/error you can run debug tools like enforcer or muforce (needs MMU).

If 80000003 is Illegal address access (ie: odd) does the odd refer to one of the CIA chips because I’ve been getting GURU’s even running some of my script files and at random times.

No, the odd refers to the address which is odd. 68000 can only access even memory adresses. Only bytes may be read from odd addresses.

For example

lea $40001,a0
move.l (a0),d0

will cause this guru.

It could be caused by running 68020 programs on 68000 (although this would more likely crash with illegal instruction).
Or it might mean that your RAM is damaged.

I’ve done extensive ram system tests and checked the integrity of the offending program all proved negative. Do you think it could be hardware related i.e. CPU or any of the custom chips?

MaxTransfer set correctly? Random crashes can happen if large data files are corrupted. Random "object is not a load module" messages can appear if large program files are corrupted. Large = bigger than 128K.

Could be some program you downloaded from Aminet, made for higher than 68000 and expecting the higher CPU to handle odd address word/longword addresses. If it's your own program, check that Asm-One or such is set to 68000 or it won't report odd address errors.

Has anyone thought about asking the first question of them all?

What were you doing when this happened?
Which software and which version were you using?
Can you reproduce this error?

Does it happen "always" or just "sometimes"?

Well I’ve been trying to use a printer on my Amiga. I downloaded some drivers. I used DosTrace from Aminet and at the point of the crash it was calling the particular driver prefs was set to. It must be for 68020+ systems. Many thanks to all that tried to help.
