    i have a pm 8600 and was wondering if the 8 scsi device limit is for the hole machine or per bus (witch it has 2 of [3 if you count the external one])

    I honestly think it is 8 per bus. On my 7100, i connected 5 devices and all of them were working.

    Do you have the Mach 5 cpu (the 300mhz one)?

    The external and one of the internals are really the same bus, so you have the 8 device limit (taking into account that the SCSI controller itself counts as one.)

    Also note that some versions of the Mac OS slap all busses together, making it limit artificially to only 8 devices, even though you should be able to 'double up'. I believe 8.0 and higher remove this.
