In 1980, software company Sorcim introduced SuperCalc, a spreadsheet program with major improvements over VisiCalc. It was able to run on any system that supported the popular CP/M operating system. The Osborne-1 included a free copy of the financial software along with it’s bundle of programs, a big boost to the popularity of the machine. Later versions of the software for DOS and Apple were introduced.

SuperCalc was one of the first spreadsheets capable of iteratively solving circular references. The company was later purchased by Computer Associates in the mid 80s where it was marketed as CA’s line of SuperCalc products. It would eventually be eclipsed by more powerful programs such as Excel and Lotus 1-2-3.
