AMIGA.RESOURCE.CX (AMIGA 3000):
The built in SCSI host adapter - based around the Western Digital 33C93 SCSI controller - supports up to seven devices connected simultaneously. The controller's configuration is stored in a NVRAM powered by the same battery which the clock is.
SCSI Problems
The A3000 may suffer SCSI related problems when several SCSI devices are attached to the bus. The most common are random SCSI bus lockups, especially with CD-ROMs and tape driver and random checksum errors when copying large files between devices. These problems can, in most cases (providing termination and jumpers are correct) be attributed to the WD33C93A SCSI controller chip in the A3000. Most, if not all, A3000s shipped with the WD33C93A-PL 00-04 chip revision. This chip had known bugs when multiple devices were present on the SCSI bus. The WD33C93A-PL 00-08 chip revision addresses and fixes the above problems.
