Previously we got this from Sussman’s desk drawer: ITS 138 from ~1967 found

Now several more listings are being processed:

An excellent endeavour!

I typed in the LISP C54 compiler and had it run on a modern Lisp by way of a Maclisp emulator. It emits LAP code for the PDP-6.

I wonder if it would run on the CADR emulator’s version of Maclisp.

Possibly, since the CADR Lisp was quite close to Maclisp. A problem I had to solve running in Common Lisp was that many variables need to be dynamically bound. I’m not sure how that would work on the CADR.
