open-in-new
<p>Applied Digital Data Systems, Inc. (ADDS), was a supplier of video display <a href="/facts/Computer_terminal/fSlx05qV">computer terminals</a>, founded in 1969 by Leeam Lowin and William J. Catacosinos. Lowin simultaneously founded Solid State Data Sciences (SSDS). SSDS was one of the first developers of the MOS/LSI integrated circuits that were key to ADDS's product line. </p><p>It became a subsidiary of <a href="/facts/NCR_Corporation/1vfttHoo">NCR Corporation</a> in 1980, which sold the <i>Mentor 2000</i> professional <a href="/facts/Computer/SQe1aK05">computer</a> in the <a href="/facts/United_States/P0sCdLe5">United States</a> in 1986. </p><p>The <i>Mentor 2000</i> ran at 5 MHz using a <a href="/facts/Zilog/sB6jH5vw">Zilog</a> processor, 640 KB RAM, and included one 60MB <a href="/facts/Hard_disk/kekLSGSE">hard disk</a>. It used the <a href="/facts/Pick_operating_system/LSXLknzu">Pick operating system</a> and <a href="/facts/Database_management_system/VYcpkevb">database management system</a>. It was able to manage 16 or 32 video terminals at once. </p><p>ADDS (along with NCR) was later part of <a href="/facts/AT%26T_Corporation/BfsX7eX2">AT&T</a>, then independent briefly before being acquired by <a href="/facts/SunRiver_Data_Systems/ECrUNfjQ">SunRiver Data Systems</a>. </p><p>However, their version of the Pick operating system was acquired by Pick Systems Inc, now called <a href="/facts/TigerLogic/R3F7QgKQ">TigerLogic</a>. That version is now called mvBase. MvBase was sold to <a href="/facts/Rocket_Software/ScXRxM95">Rocket Software</a> in 2013. </p>
