   Hi, y'all!   
      
       Almost exactly two years ago I made a run at translating the MS/   
   DOS version of version 3.01 of Turbo Pascal so that it would run on a   
   system using a 6502 CPU.  I mentioned my effort in a thread in this   
   group.  But, when the futility of such a project became apparent to   
   me, I gave up on it.   
      
       Recently, two disassemblies of the CP/M version of TP v3 became   
   available to me.  I've written a program in Turbo Pascal that   
   translates the source files for a standalone version of the TP   
   compiler, created by Werner Cirsovius.  The output of the translator,   
   when assembled, creates a 6502 compiler that is robust enough to   
   successfully parse the source file for the translation program.  At   
   the moment, the 6502 compiler is a cross-compiler in that it generates   
   Z80 machine language, not 6502 machine language.  That way, I can take   
   test source files and compare the output of the 6502 compiler against   
   the output of the Z80 compiler to find where the 6502 compiler is not   
   compiling correctly.
