The 8500 has 2 SCSI buses. The internal is Fast SCSI 2 (10 MB/sec), using a standard 50-pin connector. The external is plain SCSI 2 (5 MB/sec), using the same DB25 connector all Macs used from the Plus through the beige G3s. You can connect 7 devices to each bus. Any SCSI 2 (or later) compliant device should work, given an appropriate adapter, as needed, but it will be limited by the speed of the bus. So, if you connect a SCSI 3 Ultra Wide 160 hard drive to the internal chain with a proper adapter, it should work, but only at 10 MB/sec, not the 160 MB/sec the drive is capable of.
I can send you the service manual PDF, off list, if you'd like. On Thursday, October 11, 2001, at 04:51 AM, Richard Kavanagh wrote: > > Hi there, > > Newbie question, please be patient!.
