I'm interested in studying historical implementations of garbage   
   collection in early programming languages (BASIC, Lisp, etc).  I'm   
   especially interested in language/runtime interface descriptions.   
   Does anybody have references they can share?   
      
   [My LISP 1.5 manual says they used a straightforward mark and sweep   
   GC.  The only complication was that list storage cells had a free bit   
   they could use for marking, while cells used for strings didn't so   
   it was a separate area and they used a separate bitmap.  I'm fairly   
   sure that early Dartmouth BASIC was all static allocated, no GC. -John]
