Pretty cool to get hosted access to Interlisp-10 on a Dec-10. A bit of boring personal history: I think that it was in the late 1970s that I very randomly got access to Lisp on my company's Dec-10. I had been using Pegasys Lisp on my Apple II so Lisp languages were already ‘imprinted’ on my brain. I started teaching a lunchtime class in Lisp at work, and that ended up opening up a lifetime of professional opportunities.

BTW, there is a pretty good InterLisp-D port for macOS that is fun to play with.
