A strongly typed logic programming language with numerical constraint-solving over the natural numbers, developed by Paul Voda <> at UBC in 1988. Trilogy is syntactically a blend of Prolog, Lisp, and Pascal. It contains three types of clauses: predicates (backtracking but no assignable variables), procedures (if-then-else but no backtracking; assignable variables), and subroutines (like procedures, but with input and system calls; callable only from top level or from other subroutines).

Development of Trilogy I stopped in 1991. Trilogy II, developed by Paul Voda 1988-92, was a declarative general purpose programming language, used for teaching and to write CL.

A company founded in 1979 by Gene Amdahl to commercialize wafer scale integration and build supercomputers. It raised a quarter of a billion dollars, the largest startup funding in history, but could not create its 2.5" superchip. In 1984, it abandoned supercomputer development and later the superchip project. In 1985, Trilogy acquired Elxsi Corporation, a manufacturer of VAX-compatible systems, and eventually merged itself into Elxsi.

The Trilogy Superchip
The 2.5" square superchip was never completed, because it was far ahead of its time. Although chips from several semiconductor manufacturers have subsequently increased in size, there is no single chip as large as the Trilogy Superchip. (Image courtesy of Elxsi Corporation.)
