Turbo C 2.01

The old but famous Turbo C 2.01 for DOS is available for free from the new owners of the (formerly) Borland development tools. This was a well-loved compiler from the MSDOS days, known for its fast compilation times, integrated development environment ("IDE"), and (DOS-based) graphics library.
