RE: Transfer a 8250 diskette

Why is that? I have always used the '@'. What is it supposed do? What does
it really do?

Right.

BTW: Because of the "disaster" of this functionality ("@") with the 2031,
1540 and 1541, I would not recommend to use this at all. It is too easy to
use it accidentially on these other devices, with probably catastrophic
results.

Bottom line:
  NEWER EVER USE THE SAVE-WITH-REPLACE (@) FUNCTIONALITY ON A CBM FLOPPY
  DRIVE.

Regards,
Spiro.
