I am also wondering about disk formats.  I would
like to convert my homebrew system from 8" SSSD
to a 5.25" format.  Which format should I use?
Has anyone ever compiled a list of formats?

I assume a format description would include the following:

Recording format:  IBM (SD or DD) or Apple.
	This would also include definitions of gaps, CRCs,
	address marks, etc.  These are the truly controller-
	dependent characteristics.  

Number of sides and tracks:
	These are drive-dependent characteristics.

Sector size and sectors/track:
	Controllers can almose always be programmed for this.

CP/M filesystem parameters:
	Physical sectors/sector, allocation group size,
	directory size, and the other Disk Parameter Block junk.
	Strictly software-dependent.

Has anyone ever seen a list.
