%X A generic approach to targeting occam to non\-transputer
   architectures is described. The principle is to build a
   register\-level emulation of the major design elements of
   the transputer, using native registers of the target
   hardware, and reuse the standard occam toolset compiler with
   as little alteration as possible. The porting effort thus
   reduces to an architectural mapping rather than involvement
   in the compiler and code\-generator. An immediate payoff
   comes from reuse of a well\-developed and sophisticated
   compiler. An important scientific question, with relevance
   to efficient and portable parallel computing, is whether the
   crucial benefits of transputer architecture (such as the
   very low overheads for the management of processes and
   events) can be transferred through such emulation. We report
   some initial results for SPARC\-based targets.
