SCSI ID's are prioritized, ID 7 has highest and ID 0 has lowest priority.
Usually (but not always) the SCSI card has ID 7.
I used to run a BBS system with two BERT (MK) SCSI interfaces. 2 Computers
accessing the same harddrive. I believe I had ID 7 and ID 6 for the
interfaces (they're configurable at boottime) and ID 0 for the harddrive.
Sometimes I would add a ZIPdrive at ID 5.
You could get SCSI bus-lockups if you wrote data to the harddrive at the
same time from 2 computers, but there were never problems with reading.
Besides, there was a special DOS version (2.33 if I recall correctly) with
which you could press CTRL-BS and it would solve the bus-lockup. With
normal DOS I would just reset the computer that hung and everything was
okay again.
