For the A2000, there are three versions: the SCSI-only, the
SCSI+8, and the new '030+RAM+SCSI accelerator board.

There are a few DMA-related problems with certain revisions
of the A2000's motherboard (among them 4.3), but all of them
can be upgraded (see the Commodore TechTopics #25 for
details). Maybe Dave can comment ...

There are two revisions of the SCSI-only (for two different
pinouts of the DMA chip); three revisions of the SCSI+8
(rev4 added a jumper so 4-meg SIMMs could be used; rev5
added yet another jumper to fix certain problems with the
4.3 motherboard); there's only one rev of the "all-in-one"
so far. This only includes revisions that are in the field.
