Hello, and thank for anyone that can help on this problem. I have a client that recently switched to my company to provide lighting solutions for there club. They have an old stage with a set of controller cards inside. I thought they were DMX due to the 3 pin xlr connections, but i tried all my dmx hardware on them with no luck. The the client brought me there old computer w/ a rs-232 to 3pin xlr plug. The computer had died some months back (before i was a vendor.) It was some type of software that handled dance floor controlling. I tried to salvage the hard drive in it with minimal luck. the most i could come up with is the old software package was named "MSI" or "ONEALSO". Pics of the controller boards.
