I take it you're an engineer and not afraid to deal with a programming
level system. In that case check out the work of Niklaus Wirth (yes, the
founder of Pascal, Modula and Oberon, and builder of numerous
workstations) at the ETH Zurich, Switzerland. There is a publication of
him called "Digial Circuit Design", Springer Verlag, 1995 and a software
system available in source code called "Lola". There is also a Technical
Report on Lola, available from the ETH FTP servers. Lola is implemented
in Oberon (the language) and runs under Oberon (the system). Various
implementations of both exist for the Macintosh. The system is a bit
awkward at first (it takes over the Mac and has its own windowing
system), but many engineers seem to like it (it's not unlike Plan-9 from
AT&T in GUI appearance).

An excellent starting point for checking out Oberon is Guy laden's
homepage at http://www.math.tau.ac.il/~laden/Ob-pkgs.html. It contains
pointers to almost anything involving Oberon, including pointer to
numerous technical reports.
