I thought it was some weird deal like, it's not SCSI, but DEC used the NCR5380
SCSI chip as the interface anyway w/the wrong protocol and cable pinout.

No but if you could borrow a TZ30 then *that* would work with the AHA1520.
I've head that the TK50Z is close to standard SCSI but I have no idea how
true that is.  Anyway I wrote a DOS utility that takes snapshots of tapes
and copies them to big DOS files, if anyone has a need to actually *do* this
(like, if you do borrow a TZ30) let me know and I'll add the code to go the
other way and put it up for FTP (after I set up my TZ30 for testing, I've
only tested against a Qualstar 9-track drive so far).  This is using the ASPI
driver that comes with all Adaptec SCSI boards and most others.
