The problems are solvable and actually, I have written several programs to
get around the problem, including a replacement handler. But these are part
of stuff that I am not really at liberty to discuss or release right now.
The truth is that software which causes a bus error exception on the A3K is
broken even though it may work fine on an A2000. The example I quoted,
SysInfo, even claims to have used enforcer in development. Until a couple
of months ago, enforcer only was aware of 24 bit address space and
apparently accesses outside of that area weren't always detected. The most
recent version fixes that. It is important for developers to be aware of
what the most recent versions of these tools are and update asap.
When the A3K first came out, I was against it because there were too many
changes to be software compatible. I think most of the kinks are out and
having the chance for a cheap 040 card, I bit the bullet and went for the
A3K. I'm happy I did.

As far as A3000 SCSI, I have no problems with it. I have a recent
motherboard and 2.04, which seems to be OK to me. I have two hard drives, a
CD-ROM, and a SCSI scanner on it and it works just fine. While the hardware
uses some of the same components as the 2091, it is considerably different
as it can DMA to any address, and can move data 32 bits at a time, making
it potentially faster.
