The 16-bit [[minicomputer]] designed by Marvin Minsky was initially just named the '''2500''', 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]].
