Note that I have stopped actively supporting TurboGo!
While you are still able to download the program if you wish,
there are much better programs these days
to help you to play or learn the game of go.
Read here for more information.
As you may have read already, TurboGo used to be a DOS program, written in Borland Pascal. But then Borland created Delphi, which is Visual Pascal for Windows. In my personal opinion, this is the best programming language in the world right now, and I decided to use it to create a Windows version of TurboGo.
The ease of Delphi and the speed and possibilities of 32-bit coding give me a lot of ways to improve on TurboGo. That is the reason that I decided to stop improving TurboGo for DOS and to focus on TurboGo for Windows. TurboGo for Windows is now fully 32 bit, and is working faster and better then ever before!
