Thanks to all respondents to my request. Here are the answers for restoring NMR
data from old DC300XLP tapes to SGI (I only verified the first one):

1. If an appropriate tape drive is available on the SGI:
a. change directory to restore to.
b. 'mt rew' (to rewind tape)
c. 'dd if=/dev/rmt/tps0d7 conv=swab | tar -xvof - filename' (optional, if
no name given, all archive will be restored, tps0d7 is the tape device on
SCSI7).
d. If more than one archive on tape, after 'mt rew' do 'mt fsf 1' which
will move to the second archive, then 'dd if=....'. For third archive 'mt fsf
2', a.s.o.

2. a. 'mt -f /dev/rmt/tps0d4 retension' (a good idea to retension)
b. 'tar xvf /dev/rmt/tps0d4ns filename' (apparently this was a drive on
SCSI4).
c. If more than one archive on tape, 'tar xvf /dev/rmt/tps0d4nrns (no
rewind, no swap).

3. Find an X32 with ethernet, restore there then ftp. No problem then to use
XWINNMR2.0 for processing except for a possible message of wrong metafile. Need
to do an rpar from a good dataset to solve this.

4. Find a friend with an X32. (Thanks for the two offers!).

George
