UCSD PASCAL (P-system) P-code - test-drb@ccmp.vtda.org

...
  I have a bunch of books, discs, etc for the Apple II,
and I "may" still
 have UCSD Pascal on some 8" Terak floppies. Pascal was the language of
 choice for Mac work for a number of years, then C and C+ etc. kind of
 dropped on everybody. Messy at first as all the header files were setup as
 calls to Pascal programs in the early Mac software developer stuff. IIRC it
...
  was AlSoft that had a program/patch etc. that allowed
MIDI support on a Mac
...
  that was all in Pascal. I talked my wife into
reworking the headers for use
...
  with C programs, and sent it back to AlSoft and they
used it, but I never
 heard anything back from them about it. Really POed me at the time. 
I was told, but have never confirmed, that Apple had the source to
UCSD Pascal, and that Larry Teslar used it as the basis for Clascal, 
the Pascal-variant (no pun intended) compiler used for Lisa and initial
Mac cross-development. Then they hired Niklaus Wirth to go from Clascal
to Object Pascal.

I still think Object Pascal is the *best* implementation of Pascal
ever... the linker could determine what methods could be statically
bound, keeping them fast, and leaving the rest dynamically bound for
polymorphism. Unlike Borland's Pascal(s) [this may have changed by
the time of Delphi), you could pass procedures and functions as
arguments to procedures and functions.
