Wanted - 'Disk Tools' floppy or image

Hello,

I have a friend who has a failed PowerBook 140.  I am seeking a 'Disk 
Tools' 3.5 floppy, or image for the floppy, that will boot a PowerBook 
140 from the diskette drive.  

Suffice to say, the 'older software' page at Apple doesn't seem to 
include a the 'Disk Tools' image (as far as I can tell).  The PB 140 
sup****ts 7.0.1 - 7.5.3, and a 'Disk Tools' from that range should work.

If  you know where there is a downloadable image or 3.5 disk, reply here.

Thanks,

Mike
