<< So, if one has SCSI Manager 4.3 loaded (it's an extension as well as built into ROM in later machines) does the Quadra 900 support a full 14 SCSI devices on its two SCSI busses (7 each). Or is it still limited to seven total?
With SCSI Manager 4.3, the limitations are something like six physical SCSI buses, with either 7 (narrow) or 15 (wide) devices on each, as appropriate for the HBA.
You can easily get four buses on the Q950, and the WGS 95 does exactly that, but not under MacOS.
That's good info to know, but it doesn't address my question, which was whether SCSI Manager affects the two built-in busses in the Q900. Put another way, does installing SCSI Manager 4.3 separate the two built-in busses logically, so that they have independent SCSI ID management.
According to the Apple Docs, when the Q900 was released, if you have a device on a SCSI ID on one built-in bus, you could not use that SCSI ID on the other built-in bus. SCSI Manager 4.3 has the potential to correct that, but does it in fact do so on the Q900?
