- Thanks for the idea. Could none termination really cause the bus to
- appear blank? More information on the configuration. I connected the
- external adpater with a standard Mac SCSI cable. The wiring inside the
- case has either end of the ribbon cable attached to the external SCSI
- connectors. The middle of the ribbon cable goes to the adapter. I
- connected the Mac to one of the external connectors and an external
- terminator to the other connector.
-
- Here are some ideas that I thought of. Could any of these cause the
- problem:
- 1. Double termination. Could an external and an internal terminator
- cause this problem?
-
- 2. Termination on the internal Apple drive. Do I need to do anything to
- the Apple drive inside the Mac?
-
- 3. Address collision. Could this happen if both the internal and
- external drive were on the same SCSI address?
-
- Thanks for any more help.
