&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The 16-bit [[minicomputer]] designed by Marvin Minsky was initially just named the &amp;#039;&amp;#039;&amp;#039;2500&amp;#039;&amp;#039;&amp;#039;, and had dual [[display]]s: one for text and another for [[vector graphics]].  It was meant to run [[microcode]] to implement [[Logo]], but the size of the [[firmware]] [[RAM]] precluded that.  Danny Hillis wrote firmware for a Datapoint 3300 terminal emulator with additional commands for turtle graphics.  2500 terminals were typically attached to a host running Logo: the [[SITS]] [[PDP-11/45]], an [[LSI-11]] based machine called the [[General Turtle|3500]], or [[Unix]].&lt;br /&gt;
