I have a Rogers 320 Trio theater organ with no internal speakers but a Leslie 247 credenza style speakers on the left and a Rogers RW-40 extrenal on the right. I plan to midify the Rogers organ and want to run the sound from the computer output to those two speakers but have no idea how to interface between typical amp and speakers output to the speakers being Leslie and Rogers (pin connector versus just a couple of wires or RCA jacks) -- can this even be done?

Sorry if I'm being lengthy but I'm an electronics moron!
