Yes.

There is no difference in SD or DD drives.  It is the controller that 
makes the difference.


The Extended Color Disk Basic ROM only knows how to read/write SSDD 35 
track drives.  The other operating systems for the cococ can use DSDD 
and DSSD disks of any  number of tracks.

Tandy originally sold 35 track SSDD drives, and then sold 40 track SSDD 
drives, and finally sold 40 track DDDD drives.

So what you have depends on when you purchased it.  I replaced the 35 
track SSDD drives with 40 track DDDD drives as a matter of course.

Is that the state where they just redid the election, or the one where 
they have trouble counting? :-)
