Vizastar was the first integrated software package for the Commodore 64 home computer. At the time of its introduction it was the only package for the C64 with features comparable to Lotus 1-2-3, including spreadsheet, database and graphics components. It had the ability to split or merge files between the database and spreadsheet components and could split the screen into up to nine windows. It was later ported to the Commodore 128.
