Gene,
I's an open source project. All the documents are on GitHub. This is the manual https://github.com/svn2github/transistortester/blob/master/Doku/tags/english/ttester_eng112k.pdf Here is the top of the project https://github.com/svn2github/transistortester Source code in C++ and schematics are all there.
