I had this tape in my hands in the spring of 1998 at Case Western Reserve
University (Cleveland, OH, USA), but was not able to read it entirely without
errors. Only the first 15 files could be read without errors. They contain the
installation system, the root filesystem dump(8) image, and the following
standard subsets:

ULTBASE420
ULTBIN420
ULTINET420
ULTNFS420
ULTUMAIL420
ULTDL420
UWSSER420
UWSX11420
UWSFONT420
UWSFONT15420
UWS3DFONT420

The tape also contained a lot of optional subsets, but a read error in the 16th
file preventing me from reading any of them. Unfortunately they contain some
really essential things, including most libraries, troff/nroff, and man pages.
These subsets were:

ULTPRINT420
ULTMH420
ULTACCT420
ULTPGMR420
ULTINTLRT420
ULTINTLPGMR420
ULTCDABASE420
ULTCDAPGMR420

ULTSEC420
ULTSMSCAMP420
ULTPRESTO420
ULTMOP420
ULTUUCP420
ULTVAXC420
