* '''IBM''': 160k single-sided. 40 tracks of eight 512-byte sectors each. Sectors numbered &01 to &08. Provided for compatibility with CP/M-86 (and DR-DOS 1.0). Used by very few CPC purchasers, but Locomotive Software stated that this was invaluable for cross-assembly. The useable capacity is 158k.
* '''Vendor''': Term used for System format discs with no software in the reserved tracks. The useable capacity is 169k.
All these disc formats use a CP/M based filesystem.
