When I were one ("Ten years ago, I couldn't spell 'engineer', and now I
are one"), 8K of 12-bit words was all we had. But a Lisp interpreter
existed, though it could only use 4K. Symbols and fixnums and pairs,
oh Ghu!
Hah! The source code (in PDP-8 assembly language) for that same
interpreter is at http://www.timgorton.com/pdp8/lisp3.pal . It starts,
as most PDP-8 programs start, by implementing a rubout handler: it was
too expensive and messy to use the TTY driver on OS/8, so most programs
bypassed it. The part most interesting now is probably the end, where
the oblist is, and the various comments scattered through it.
