The 16-bit minicomputer designed by Marvin Minsky was initially just named the 2500 for the target price, and had dual displays: 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 3500, or Unix.
