Now there are > several programs running around, including a Motif icon version, Well, I set switch 6 on. But got only 1 track continuously. (Boring). I can't set the SCSI ID to 0, the 2 disks are at 0 and 1 and I don't know where the address jumpers/dip switches are on those disks. (No manuals or docs of any kind on the hardware). Could someone tell me where some of these CD player programs are located. I'll be glad to send media and postage to get hold of it. Thanks!
