This model is an extension of the previous NEA model which implemented with extending the functions to include an automatic 8-digit multiplier. but the manual clearing levers retained the same. From the model ESA-0 engineers have added a motorised clearing mechanism. It included three additional keys at the lower front. The iron frame of this non-printing electric pinwheel calculating machine is printed in dark green color. Fully automatic addition, subtraction, multiplication, and division was available in this calculator. Additionally, clearing of registers was done electrically.<\/p>\n<p style=\"text-align: justify;\">This calculator contains five function keys and three tab keys. The key tops were made of plastic. There is a lever on the front left sets the machine for multiplication, addition, subtraction or division.<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_separator color=&#8221;white&#8221;][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column width=&#8221;1\/2&#8243;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1618823526815{border-top-width: 0px !important;border-right-width: 0px !important;border-bottom-width: 0px !important;border-left-width: 0px !important;padding-top: 5px !important;padding-right: 5px !important;padding-bottom: 5px !important;padding-left: 5px !important;background-color: #000000 !important;}&#8221;] Model: Facit Model ESA-0, S\/N 349720, 1953 Developer: Karl Rudin Manufacturer: Atvidaberg-Facit, Sweden, Released in: 1949-1956 Specifications Digits- 9 keyboard, 8 counter, 13 accumulator Dimensions- 280W x 260D x 180H Weight- 12.4 kg &hellip; <a href=\"http:\/\/emuseum.ucsc.cmb.ac.lk\/?page_id=1023\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;Facit Electro Mechanical Calculator (1953)&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"categories":[86],"tags":[],"_links":{"self":[{"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/1023"}],"collection":[{"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1023"}],"version-history":[{"count":9,"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/1023\/revisions"}],"predecessor-version":[{"id":2195,"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/1023\/revisions\/2195"}],"wp:attachment":[{"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1023"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1023"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1023"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
