=== A1-S Upgrade Kit ===
Vortex offered an upgrade kit consisting of a bare 5,25" drive (BASF 6138) and an installation manual, allowing to upgrade a single F1-S drive to a dual F1-D drive. To do this, one simply had to install the additional drive in the free slot of the drive case.

== Z-Drives (180K/side) ==
These are less expensive 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. The Z-drives were basically S-drives without a Vortex controller and CP/M license.
