For the curious where this came from, it’s from a FIG (Forth Interest Group) publication. FIG publications typically consisted of a colored card stock cover stapled to a stack of photocopied pages. This was how they produced their famous FIG Forth listings for the various CPUs (6502, PDP-11, 8088, etc.). I recall my friend picking this up at our local technical book store. They carried all sorts of arcane stuff like the FIG listings. Definitely in the deep end in that book store compared to you local B. Dalton. A very cool time where it was anything goes in terms of computing.
