CONSULT THE ORACLE (1K ZX81)
by D A Walker, London SE13
from Your Computer (October 1981), page 71

THE RND function in the I-Ching program does not seem very oracular to me 
perhaps the nearest analogy to tossing a coin the ZX-81 can provide is to
discover at a random moment whether the frame count is odd or even. This
could bring the psychic factor into play.

I have devised this no-frills program to fit into my unexpanded ZX-81. It
lets you know the result of each toss and builds a hexagram with moving
lines  if any  in the middle of the screen. This is sufficient for
consulting the book. The string in line 10 can be used to save on cassette.
