MIL-HDBK-1280

Abstract

This standard establishes the assignment of the 128 characters of the Military Standard Code for Information Interchange and 54 of the 57 "American" characters of USASCSOCR X3.17-1966 to keys in a typewriter-like keyboard arrangement for application where the textual information has a high alpha content. This standard also establishes the assignment of the same character sets in a typewriter-like keyboard arrangement for application where the textual information usually has a high numeric content. (See <a>Tables I</a> and II.) <b><u>Intended Use:</u></b> <a href="#JANJFAAAAAAAAAAA-X92">Figure 3</a> is intended for office typewriters which are used to prepare documents that, in turn, will be processed through optical character recognition equipment. The notational system is intended solely as a uniform, convenient method of expressing the nominal relative position of keys within any keyboard arrangement. Physical characteristics such as size, shape, skew, spacing, pitch, etc., are not to be inferred. <a id="JANJFAAAAAAAAAAA-X90" name="JANJFAAAAAAAAAAA-X90"><img alt="FIGURE 1 TYPE&#10;I, CLASS 1 STANDARD KEYBOARD ARRANGEMENT" src="" /></a> <a id="JANJFAAAAAAAAAAA-X91" name="JANJFAAAAAAAAAAA-X91"><img alt="FIGURE 2 TYPE&#10;I, CLASS 2 STANDARD KEYBOARD ARRANGEMENT" src="" /></a> <a id="JANJFAAAAAAAAAAA-X92" name="JANJFAAAAAAAAAAA-X92"><img alt="FIGURE 3 TYPE&#10;II, CLASS 1 STANDARD KEYBOARD ARRANGEMENT" src="" /></a> <a id="JANJFAAAAAAAAAAA-X93" name="JANJFAAAAAAAAAAA-X93"><img alt="FIGURE 4&#10;KEYBOARD ARRANGEMENT NOTATIONAL SYSTEM" src="" /></a> <a id="JANJFAAAAAAAAAAA-X94" name="JANJFAAAAAAAAAAA-X94"><img alt="Table I.&#10;MILITARY STANDARD CODE FOR INFORMATION INTERCHANGE" src="" /></a> <a id="JANJFAAAAAAAAAAA-X95" name="JANJFAAAAAAAAAAA-X95"><img alt="Table II.&#10;Optical Character Set." src="" /></a> <br>
