Mesa
Xerox PARC, 1977.
System and application programming for proprietary hardware: Alto, Dolphin, Dorado and Dandelion. Pascal-like syntax, ALGOL68-like semantics.
An early version was weakly typed.
Mesa's modules with separately compilable definition and implementation parts directly led to Wirth's design for Modula.
Threads, coroutines (fork/join), exceptions, and monitors.
Type checking may be disabled. Mesa was used internally by Xerox to develop ViewPoint, the Xerox Star, MDE, and the controller of a high-end copier.
It was released to a few universitites in 1985.
Succeeded by Cedar.
