I have it, though only on a pixel format; it used to be at
which is a copy of the one in the Berkeley library. Corbett says that the
thesis TeX sources, he has only on an old tape which he does know if he
can read anymore.

The Aho et al book mentions both this reference and a "more efficient
LALR(1)", but it does not say if it is the algorithm of the reference. The
book at http://www.cs.vu.nl/~dick/PTAPG.html explains how to produce
non-deterministic parsers from grammars.
