Patch for Older Versions (To work on faster processors):   tppatch.exe
Starting with 300MHz Pentium II processors GoTools like all other programs written in Borland Pascal showed a runtime error 200 at startup. This comes from dividing through zero. It is a bug in the Borland Pascal initialization of the delay-function which only became apparent when faster Pentium II processors were available. To fix any old version of GoTools (or any other Borland Pascal exe file) you have to download tppatch.exe, to copy it into the directory where you have the file, for example, gotools.exe and run the command   tppatch gotools.exe  .
