Hello, If you are still interested, I have a total of 11 compatible tapes (8 Teac CT-600N and 3 Maxell CS-600XD). All are used and have used labels. As far as I know, they all still work. (I still have the tape drive as well, but have no longer an operating Apple system, so I cannot check these). If you are interested, please let me know. romboc
