Abstract

THE LINCOLN KEYBOARD--A TYPEWRITER KEYBOARD COMPUTERS IMPUT FLEXIBILITY* DESIGNED FOR A. VANDERBURGH** A new typewriter keyboard, for direct and punched paper tape computer input will replace the usual commercial keyboard with 88 characters chosen for the convenience of p r o g r a m m e r s . The Lincoln Keyboard is expected to facilitate the programming of algorithmic processes and should allow considerable flexibility in assembly and utility routines. The 88 characters are incorporated in the 44 key standard typewriter design. The characters chosen for the new keyboard are as follows: 1. Block English Letters 26 2. Standard Arabic Numerals 10 8.
