My Roland Compu Music System interface card started to smoke recently. This interface allows the Compu system to be loaded into an AppleIIE (ancient system). Can anyone help in locating another Roland Compu Music system. They were available in Jan. 1983 to Nov. 1983. I have the one for the Apple although there are others for IBM PC's. This periferal allows me to play the ARP2600 analog synthesizer through this. My ARP is fine yet I need someone with the Roland system who wants to sell or knows how I can get this interface card fixed. Please help.
