I heard back from Fred Wright:

 "Although I wasn't at SC in 1972, I'm pretty sure I would have heard of
  the SC-4 if it had ever existed.  The document you linked was just a
  proposal, and I imagine that that's as far as it ever got.  AFAIK, SC
  didn't create any full-fledged computers between the SC-15 (1970) and
  the SC-30 (1983)."
