Microsoft Multiplan 4.2

Microsoft Multiplan 4.2 is a spreadsheet application from the years when electronic spreadsheets were still something of a revelation. Multiplan lets users organize figures into rows and columns, perform calculations, and build practical financial or business models without filling an entire desk with paper. Its DOS interface is austere by modern standards, but the underlying concept is remarkably powerful: change one number and let the computer recalculate everything connected to it. That simple trick helped transform office computing. Multiplan may not have the visual sophistication of later spreadsheet giants, yet it represents an important stage in the development of software that became essential to business life. Using it today requires adjusting to keyboard-driven navigation and a more deliberate workflow. There are no colorful charts begging for attention, just numbers patiently waiting for someone to make a questionable financial forecast.
