A hobby coding project of mine, Costa is a program which runs on top of MS-DOS or compatible operating systems. The aim is to replace the DOS-prompt with a clean, user-friendly interface – a so called GUI (Graphical User Interface). Costa comes with full mouse and keyboard support, and a bunch of useful accessories.
Most development took place between 2004 and 2012, when version 1.0 was released. Since then I have moved on to other projects, and now rarely fire up the code editor to work on Costa.
Costa has it’s own homepage, where you can learn more and download the program free of charge.
