Hmmm. Went to that site listed at the bottom of the SLU (HTTP://LIGHTANDSOUNDUNIT.WEEBLY.COM) and it opened on some kind of tutorial/lessons on "Light and Sound". Jack had mentioned that SLU boards may no longer be available. Oh well, with the information and suggestions you provided, I will have these cut wires soldered to 8" wires terminating with 2 pin female DuPont connectors and play around from there. Thanks again.
