Hello Steve,

Yes your HP logic analyzer (in conjuction with the FuturePlus Systems
Preprocessors) can store only transactions to certain address ranges.  You
can also specify only certain types of transactions to certain address
ranges.  Also you can use the GNT# signal of the SCSI bus master to further
qualify the trigger.
See our WEB page at www.futureplus.com or give me a call and I'll work up a
sample trigger and send it to you.  If you like you can demo one of our
cards and try it our for yourself.
