=== Second Drive A1-S Upgrade Kit ===
Vortex offered an upgrade option that allowed an F1/M1-S single drive to be upgraded to an F1/M1-D dual drive. To do this, one simply had to install an additional BASF 6138 drive in the free drive slot of the SF1-drive housingS case.
=== FDA-1 3" Drive Adapter ===
== Z-Drives (180K) ==
These are basic and less expensive ''low-capacity'' drives and were meant to be directly connected as B drive to a CPC 464 with DDI-1 or a CPC 664/6128. Since these drives do not ship with an own controller or a VDOS ROM, they do rely fully on AMSDOS and thus only 40 tracks can be accessed.
=== Variants ===
* '''M1 - Z''' Single 3.5" drive with power supply with ribbon cable (does not come with interface containing FDC or [[VDOS]])

=== A1-Z Upgrade Kit ===
Vortex offered upgrade kits consisting of a controller, manual, CP/M license and utility disk which upgraded a Z-Drive to a S-Drive, suggesting actual floppy disk drives were identical between the S- and the Z-Series.
== X-Drives (720K) ==
