  Well known machines, yes. I don't have access to them anymore. The
Honeywell DPS series (36 bit) has 400000000000(8) for f.p. zero and
xxxxxx00004x(8) for byte pointer (x's are address bits). I believe that
some DG models have char ptrs which are non-zero when NULL, but I
haven't looked at one in close to ten years.

  Can someone help on this?
