"WD33C93A-PL 00-08 SCSI controller chip upgrade
As you may know, there are several problems that can occur when adding
additional SCSI devices to the SCSI bus on the A3000. Most common are
random SCSI bus lockups, especially with CD-ROMS and tape drives, and
random checksum errors when copying large files between devices. These
problems can, in most cases, be attributed to the WD33C93A SCSI controller
chip in the A3000. Most, if not all, A3000's shipped with the WD33C93A-PL
00-04 chip revision. This chip had known bugs when multiple devices were
present on the SCSI bus. With a single device, problems rarely occurred.
As soon as the user started to add devices to the bus, the problems
mentioned above would start to appear. The WD33C93A-PL 00-08 chip revision
addresses and fixes the above problems. I would like your user group to
know that I am a source for this upgrade chip"
