Also running on the emulator: PDP-10 Logo, PDP-11 Logo, Applle II Logo. The emulator doesn't support the robot arm yet.

I have nightmares about that! ;) https://donhopkins.com/home/catalog/hyperlook/TalkInterfacing.gif https://donhopkins.com/home/catalog/hyperlook/TalkInterfacin...

  Say, are you handy with lego?

    Of course, I just try not to step on them.

This robot arm??! Yikes! It's getting very huggy there.

Thank you for doing this, Lars, and thank you for all the amazing historical research and preservation you are doing on the PDP-10 and the origins of operating systems, Lisp, Logo, symbolic math Macsyma, and all of the software and system zeitgeist that produced Logo. We always felt like we were packaging up what our AI lab hacker culture was like, in "mind-sized bites" as Seymour said.

  Thanks for the kind words! I'm grateful for the quirky, fun, and interesting work and research that was done, and glad it much of it has been preserved. (Also sad some of it has been lost.)
