Besides ITS proper, there were many subsystems that were more or less tied to ITS, some of them with their own operating systems. Others like the TV and XGP had dedicated PDP-11 computers running special software. Just to list a bunch: PDP-6, Logo PDP-11/45, Minsky's 2500, Imlac PDS-1, GT40, Robotics PDP-11/40.

From the offices at Tech Square, you could also call the elevator to your floor (by pressing Terminal-D), and buzz the elevator lobby door open from the comfort of your Lisp Machine (by pressing Terminal-E), via the PDP 10/11 interface on AI. Random tourists could just pound on the door, and somebody would usually buzz you in without checking who it was, just to get some peace and quiet. Lars, do you know anything about the wire wrapping robot that was on the 9th floor? Henry Minsky says he thinks either Holloway or Knight built it (Tom Knight would know), and they used it to make the CADR lisp machine boards. Those were huge freaking wire wrap planes, the size of a tabletop. Here's Marvin Minsky demonstrating the 2500: https://www.youtube.com/watch?v=c4kMzrDr4jQ https://www.youtube.com/watch?v=c4kMzrDr4jQ Cynthia Solomon's got a lot more amazing historic videos from that time: Atari Cambridge Research- parts 1-6: Introduction: https://www.youtube.com/watch?v=CR2CwKculBU https://www.youtube.com/watch?v=CR2CwKculBU Margaret Minsky demonstrates a gestural system: https://www.youtube.com/watch?v=-Wq6SQTVM9M https://www.youtube.com/watch?v=-Wq6SQTVM9M It's 1984 and Ed Hardebeck shows a gestural system and Gary Drescher shows object-oriented Logo: https://www.youtube.com/watch?v=ClKQHgIoLPc https://www.youtube.com/watch?v=ClKQHgIoLPc A force feedback joystick, a puppet machine and a program of dance and body movement are presented: https://www.youtube.com/watch?v=R3qPCZ5z0UQ https://www.youtube.com/watch?v=R3qPCZ5z0UQ David Levitt shows the music box: https://www.youtube.com/watch?v=ocwsVkqEKys https://www.youtube.com/watch?v=ocwsVkqEKys Music box with Tom Trobaugh and drum machine with Jim Davis: https://www.youtube.com/watch?v=DhA0FGsin_s https://www.youtube.com/watch?v=DhA0FGsin_s

  The elevator and door hardware was in the TV-11. The IO pins are available in the emulator, but alas not connected to anything. I have heard about the wire wrapping robot, but not who made it. The boards were made by Augat.
