Issues with A600 June Bug Rev 2D motherboard :(

[alexh]

I don't think there is any difference of any note between A600 motherboard revisions.

I'd bet money there is something you are trying to use as part of installing or using that CF card which requires an 020 CPU or FastRAM or something explaining why it works on an A1200 and doesn't on the A600.

Try a shorter IDE cable? Do you have a trapdoor memory expansion? Tried removing it?

I've never ever heard of an issue with A600 motherboard revisions for any reason.

Edit : Guru error 80000003 is indeed a RAMlib error. Indicates the opcode contains an illegal unaligned address. This is mainly due to programs issuing a 68020 memory access. Sometimes due to a too low memory stack. Data Corruption due to bad RAM. Trying to access 32-bit RAM on a 24-bit processor. KS2.x+ incompatibility.

Guru #80000003 DeadEnd alert
SubSystem : Processor
ErrorGroup : Not specified
Specification: Unaligned Address Error

On 68000 this is caused by using WORD or LONG access on odd address or by jumping to odd address or by odd supervisor stackpointer on exception.

Intel doesn't enforce integral boundaries. Motorola 68000 did, but only on 16 bit boundaries (because that was it's bus width). Then 68020 had 32 bit bus, and it had to be ok with non-aligned integers or programs written for the 68000 wouldn't work, so it stopped enforcing them as well. As an Amiga owner, I had problems with programs written for 68020 trying to access 16 bit values on 8 bit boundaries, which would work on 68020 but not on 68000.
