[comp.sys.mac.hardware] Internal HD SCSI ID#

Whoops! Last post got truncated. I am looking for help at changing the SCSI 
ID# on what was an internal Quantum 40 meg drive. Any help would be 
appreciated.

Would someone describe in detail how to change the SCSI ID# of what started 
out as an Apple Quantum internal 40 meg hard drive with ID# 0.

I have found 6 sets of jumper pins on the electronics board and am guessing 
that this is where it's done. I am in the process of turning this drive 
into an external.

Thanks in advance.

Whoops! My last post got truncated for some reason. I'm looking for an 
explanation of how to change the SCSI ID# of what was once a Quantum 
internal 40 meg HD (Apple) Thanks in advance.

On Quantum drives, you will find three little sets of jumper brackets, labelled
A0, A1, and A2. Ao is the least significant bit, adding 1 to the SCSI ID,
A1 adds 2, and A2 adds 4 to the SCSI ID when shorted. Make sure you have
found the correct pins before you short any connections.
 
At least this is what was on my Quantum 80 and 105.
