From what I heard fairly recently, some early LISP implementations were on quite small machines. One was the PDP-8 (see http://www.softwarepreservation.org/projects/LISP/other/) and that same page also mentions LISP for the ZEBRA -- a Dutch machine, with 33 bit words.
I think another was the Electrologica X1, another Dutch machine, like the ZEBRA from 1958, with 27 bit words and a base configuration of 4k words of core memory. I may be off; if it wasn't the X1, it would be the X8, from 1968, also 27 bits but more likely to be seen with 32 k or so of memory.
A lot of things can be done in small amounts of memory if you work at it, though admittedly most who have that skill probably also have white hair. :-) For example, the world's first ALGOL compiler -- a full language compiler, not a subset -- ran on an EL-X1 with 4k words of memory. And it was built by 2 people, in 6 months. Now admittedly one of those two was E.W.Dijkstra...
