@flatwhatson I am delighted to see that this effort exists! In the early 90’s I built robots that booted to s48. Jonathan Rees made scheme work brilliantly. In the late 90’s I set up a new group of robots with Kelsey’s Kali scheme. On one of my visits to NEC, I asked Richard about pre-scheme.

I think jar called it “a compiler only one person could run”, so I didn’t feel too bad that I couldn’t get it running on my own.

But that’s a story for another day.

I wish you great success!
