Peter: First, read all the manuals with the unit you have, so see if you
can't CHANGE it to CW/CCW via such as a little DIP-switch, etc.

Failing that, Mariss sent me a simple 1-IC schematic of a CW/CCW to S/D
converter, so I ASSUME he is aware of a like-simple design for "going the
other way" (S/D to CW/CCW). I could figure it out myself, if no one else
will send you some "known, working" schematic. Yeah, thinking about it, it
would also be a 1-IC simple circuit. Just let me know if you need me to
sketch and think!
