Hmm. I don't have the machine in front of me to check (I'm at work), but I
pretty sure my Osborne 1A drives are single sided not double sided. But I
have the double density modification so yes, around 180-200k per disk I
imagine. Using the PC and Imagedisk I could easy write DD single-sided
disks in a double sided (360k PC) drive though.

Terry & all,
To be clear - SD on a "360K" floppy is 180K? Yes?
NO.
Osborne SD was also single sided.
10 256 byte sectors per track. 100K.
"360K" was 9 512 byte sectors, with TWO sides used.
