This was in a rather early EN issue. They came with a one-3080 circuit
later. Quite simple design (kind of proud that I have devellopped
almost the same circuit for JH-1 independently, btw.). I can make a
little .GIF if You like ... but all in all, a MC1496 is the better solution,
and almost as available as the 3080.
