The original (corrupted) Dectape image is at

http://www.bitsavers.org/bits/DEC/pdp11/dectape/rsts/SeattlePacificCollege/158_ahl_basic_games.dta.gz

Since RSTS (and RSTS/E) natively access files from DECtape in DOS-11 format
only - I found the home block was offset in the image file (If I recall it
was not on a block boundary).  A snip of these superfluous bytes made it
readable.  The location of the original file suggests it came from Seattle
Pacific College.  Someone at bitsavers (Al Kossow) may know more about the
DECtape's provenance.
