Back in 1995, I was 22, living in the south of Germany, and was studying at our local university. I had programmed a computer game in my spare time based on the game "Atomix" for MS-DOS in Turbo Pascal and X86 Assembler.

Following are some screenshots of the game.

The external setup/configuration application, made with Turbo Vision.

Back then in the 1990s it was really fun to develop the game.

I recently made the game runnable again by installing it in a VirtualBox virtual machine with MS-DOS 6.22.

I had to patch the executables because of a bug in the Turbo Pascal runtime/compiler for faster processors. See this german c't article about details of the Runtime Error 200. Download the patching tool as "ctbppat.zip" from this location.

To play the game, locate the VirtualBox image in the "vm" sub folder and run it in VirtualBox.

Inside the MS-DOS machine, the game is located in the folder "C:\uwekeim\atoms". Start the "atoms.exe" executable.

See this file for additional documentation about the program and some cheats (all in German only).
