ISTR that you could die of old age trying to install from TU58!

Just doing a BACKUP /VERIFY to nine track 1600 BPI tape took about 
fourteen hours!  At this late date, I understand why DEC gave us 
(Princeton University) an 11/750 with RA-81 disk at an extreme discount! 
  Nobody in his right mind would have paid for it if he had to install 
it and/or do full disk backups!

I put in a few fourteen hour days doing BACKUP and RESTORE to remedy
disk/file fragmentation.  I also put in a good deal of time trying to
convince users that they should allocate a reasonable amount of 
contiguous disk space to hold their data.

Eventually, somebody wrote some software that could defragment an ODS-2 
file system without doing a backup and restore.
