The S430 system contained the main memory which consists of 256 kilobit DRAMs, 16000 gate CMOS custom LSIs for the central processing unit, and was equipped with a 4,400 gate CMOS gate arrays and other high density logic LSIs.<\/p>\n<p style=\"text-align: justify;\">S430 system was a machine with expanded functionality, and also achieved smaller size, higher speed, lower power consumption, and higher reliability which marks a great improvement in the computing industry.<\/p>\n<p style=\"text-align: justify;\">S430 has relatively closer features with S350. S340 has additional features like paging capability and dynamic address transformation (DAT) for input\/output channel operation. These new features helps S4340 to work on wider range of tasks such as data processing, office automation, CAD and R&amp;D.<\/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_single_image image=&#8221;846&#8243; img_size=&#8221;large&#8221; el_class=&#8221;museum_item&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1610944106018{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: S430 Device: System unit Released in: February 1984 Specifications Operating system: ACOS-4 Number of arithmetic processing units: 1 Max. main memory capacity: 16MB Max. number of channels: 12 Max. &hellip; <a href=\"https:\/\/emuseum.ucsc.cmb.ac.lk\/?page_id=844\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;NEC System Unit (1984)&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":846,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"categories":[204,54],"tags":[],"_links":{"self":[{"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/844"}],"collection":[{"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=844"}],"version-history":[{"count":5,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/844\/revisions"}],"predecessor-version":[{"id":2168,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/pages\/844\/revisions\/2168"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=\/wp\/v2\/media\/846"}],"wp:attachment":[{"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=844"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=844"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/emuseum.ucsc.cmb.ac.lk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=844"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
