I also have an Apple II Duodisk, which unlike the II fdd s has a DB25 pin female connector. Were these for the GS or did Apple simply upgrade the disk connections with the + or A-3. would it work on a II with an adapter ? ----------- Actually the Duodisk never worked properly on the GS. They were designed for latter model //e's. Apple redesigned the Disk 2 controller card to use the new connector. -- Kirk
