<p>An OK start</p> <p><b>New page</b></p><div>The '''Lear Siegler ADM-3A''' was a very popular early [[video terminal]]; its low price (US$955), compared to its competitors, made it a common choice. The &quot;ADM&quot; part of the name reputedly stood for 'American Dream Machine'.<br /> <br /> It was implemented entirely in discrete [[gate]]s ([[transistor-transistor logic|TTL]] family); this was long before the era of [[microprocessor]]s, or any other [[program]]mable technology.<br /> <br /> The -3A was based on an earlier model, the -3, which initially only supported upper-case, and displayed 12x80 characters; options for lower-case, and 24x80 display, were later made available. The -3A differed in supporting the ability to set the [[cursor]] to any screen location, making use with [[video editor]]s possible.<br /> <br /> ==Later retrofit==<br /> <br /> Zentec produced a retrofit card which replaced the very large original [[printed circuit board|PCB]] of the ADM-3A with a much smaller card using the [[National Semiconductor NS405 and NS455 Terminal Management Processor|NS405 Terminal Management Processor]] [[integrated circuit|chip]].<br /> <br /> ==External link==<br /> <br /> * [http://bitsavers.trailing-edge.com/pdf/zentec/Zentec_ADM3_Retrofit/ Bitsavers Zentec repository]</div>
