DSDD 8" should fit just fine on "1.2M" 5.25"

 5.25 it's been so long.  I do remember the CCS used a banking scheme that
 didn't agree with most of my systems. 
CCS did have some 5.25" disk formats (both 48tpi and 96tpi) supported.
I have no idea whether they ever used them as boot disks. 
I'd have to read the boot rom source.  Who knows it's been years since 
I read the FDC manual so it could be wired in, the controller does 
do 5.25.   I'd bet a penny there is no reason why not.
