[net.micro.cpm] 5.25 Disk Formats

wolenty@inuxd.UUCP (R Wolenty) (07/02/84)

I am trying to customize a CPM BIOS for an homebrew Z80 based
system.  I would like to know if anyone has suggestions as to 
what 5.25" SSDD disk format to use so that I might be able
to order CPM sotware in a format familiar to distributors.
Any suggestions would be welcome especially if detailed information
such as number of sectors/track and number of bytes/sector is
available.

The format that I would suggest if you are using 40 tracks is;

	256 bytes per sector
	17 sectors per track
	3 reserved tracks
	155K bytes disk capacity
	
The data architecture could be to an IBM system 34 format or modified as per Xerox


Hope this helps//Ken
