Three DSs, each one page, 8.5 x 11, dated from 1983 to 1987, all being releases for Charles Mann's 'Powersharing Series.' Signers are: Daniel Bricklin, the 'Father of the Spreadsheet' as co-creator of VisiCalc, the first spreadsheet program for personal computers, originally released for the Apple II in 1979; Robert Frankston, who developed VisiCalc with Bricklin; and Mitch Kapor, who co-founded Lotus and developed Lotus 1-2-3, which quickly overtook VisiCalc as the spreadsheet standard. Each is signed in ink in cursive and print by the subject, and two are countersigned by Mann. In overall fine condition. Accompanied by the original mailing envelope for the Kapor document.
