Hmmm...  What version of mac68k5380.c do you have?  The mac68k5380.c is
a machine-dependent part of ncr5380.c--which is #included at the bottom
of the file.  You should have at least version 1.14 of mac68k5380.c and
at least version 1.10.2.1 of ncr5380.c to be up with the latest
available sources.  Versions of mac68k5380.c between 1.11 and 1.13 had
several errors...  :-(

Hmm...   I haven't seen this...

... and I don't use a CD-ROM drive much under BSD.

*sigh*  :-(

Hmmm....  This leads me to believe that you have earlier sources than
1.14 because I was able to use the tape--last time I tried--with this
driver (the earlier (scsi.c) driver would not handle tapes well at
all--usually wedging the scsi system irrecoverably).

There's hope, but not in the next release.  I haven't touched it
for two weeks and the code is already frozen for the next
release--that's too big of a change to go in, now.  I'm hoping for
a miniroot installation from CD-ROM, ethernet, slip, ppp, tape, or
MacOS hard drive.  Perhaps even AppleShare over EtherTalk (with
the help of CAP--if it has an AppleTalk client package as well as
server).
