The Therac-25 (and several other poorly-made machines) are in a book
called "Fatal Defect: Chasing Killer Computer Bugs" by Ivars Peterson,
ISBN 0-679-74027-9... it's a bit dry at times, but has some good stories
of programmers that I'm glad I'm not :)

        After sifting through the overwritten remaining blocks of Luke's
home directory, Luke and PDP-1 sped away from /u/lars, across the surface
of the Winchester riding Luke's flying read/write head.  PDP-1 had Luke stop
at the edge of the cylinder overlooking /usr/spool/uucp.
        "Unix-to-Unix Copy Program;" said PDP-1.  "You will never find a
more wretched hive of bugs and flamers.  We must be cautious."
