Can anyboby tell me if it is possible to change the disk drive in my Technics 3000 to one of those new type floppy drives that can store 120 Mb of info?

Unfortunatly, (although I could be wrong) I believe it would not be possible. There may be an alternative - a product called megafloppy - see www.lionstracs.com

hope this helps,

Rich
