The last two digits of the six digit number is the system error number, but I don't know what the first four represent. The system errors are in hex: 01 Bus Error 02 Address error 03 Ilgl Inst 04 Div 0 05 CHK O.R. 06 TrapV 07 Privilege violation 08 Trace interrupt 09 1010 exception (!) 0A 1111 exception 0B Misc exception 0C Bad trap 0D NIL interrupt vector 0E I/O sys err 0F SegLoad err 10 FP err 11..18 can't load package 19 Out of Memory 1A SegLoad err (Code 0) 1B Bad file map 1C Stack overflow That's about it. There are some others (menu purged, etc), but they aren't documented in IM. Does anybody know what the first four digits mean? -Justin

The following comes from Dove's MacSnap_Plus_2 documentation: 01aabb = ROM Test 02aabb = RAM (Bus) 03aabb = RAM (Write) 04aabb = RAM (MOD3) 05aabb = RAM (Pattern) The aabb hex digits get expanded out to binary bits after swapping aabb to bbaa. A zero bit means OK RAM, a one bit means suspect RAM. I don't have (but would like) the mapping onto the SIMMs used on the newer machines (the Dove documentation I have only covers the 512k machine in this appendix). -- Jeffrey D.
