NoteCartridge version of the Atari Calculator which was created by Carol Shaw in 1979. Atari had never released a cartridge version. I've created this one for Carol based on the final disk version to say thank you for providing the manual that was not available anymore. In 2016, Carol provided the original assembly printouts of the never-released cartridge version. See Colleen Calculator for the scans and the source.
